ThinkPad Edge E420s now shipping for $699, E220s coming in April

  you've forgotten about Lenovo's pair of new Edge machines! Sure, they've taken a while to get to market, perhaps having been inconvenienced by a little hiccup with Intel's Core 2011 chipsets, but the first of them is now well and truly on sale and the other is looking eager and ready to go too. The 14-inch E420s is up on Lenovo's web store, starting at $699 with a 2.1GHz Core i3-2310M CPU, while its 12.5-inch sibling, the E220s, is expected on the 8th of April, judging by the roadmap doc we've uncovered below. The E420s touts what Lenovo calls an Infinity Glass display, meaning simply edge-to-edge glass, alongside a fingerprint reader, a fetching new matte black lid, a HD webcam, 4GB of RAM and 250GB of HDD storage at a minimum, and a 48.8Wh battery. A 1366 x 768 resolution is your only option, unfortunately, though you can spruce up performance by quite a bit if you opt for the i5-2410M, which does 2.3GHz at default speeds or 2.9GHz when only one of its two cores is pushed to the limit ... or should that be to the Edge?

Sony and LG price a swath of 3D HDTVs

We're still waiting on LG's ginormous 72-inch LZ7900 to make its debut on store shelves, but the rest of CES's primo 3DTV crop is rearing to ride out, with Sony's HX929, HX820 and HX720 series of LED-backlit LCD screens and LG's Infinia PZ750 plasmas now priced at Amazon. 3D-Display-info.com found Sony's locally-dimmed Bravia sets starting at $2,099 for a 46-inch HX720 with Gorilla Glass protection, all the way up to $3,799 for the premium 55-inch XBR-55HX929 with a full-array LED backlight. Meanwhile, the 50-inch LG PZ750 (with Smart TV, naturally) starts out at $1,599, while a 60-inch version of the same thing will run $2,199. Which one fits best in your den? That depends on a number of things, but we will add that the Sony sets are merely up for pre-order, while the LG units are listed as shipping within a matter of weeks.

Switched On: The PlayBook polyglot



When Apple introduced the iPad, it had but a smattering of third-party applications, but the company stressed its own. As Apple iPhone software SVP Scott Forstall stated in the iPad introduction video, "We looked at the device and we decided: let's redesign it all. Let's redesign, reimagine and rebuild every single app from the ground up specifically for the iPad."

Compare this to the strategy employed by RIM, makers of the upcoming BlackBerry PlayBook tablet. One year after the iPad's debut, Apple's head start in apps has proven a formidable advantage against the onslaught of slates announced by its competitors in the smartphone world. Some have chosen to latch onto Android and attain backwards compatibility with over 200,000 existing smartphone apps. HP, with its TouchPad as flagship, will circle its wagons of PCs, printers and phones around the webOS platform. However, the announcement this week that RIM's BlackBerry PlayBook will support Android apps says much about how the company sees its position in the tablet wars.

C and C++ are the native routes to app development on RIM's long-gestated tablet, but they certainly not the only ways. Flash / Adobe AIR and HTML5 will also be supported as will several popular game engines. Android and Java apps will be accommodated with add-on players and distributed via RIM's App World, RIM's app marketplace. The ability to run Android apps without the underlying Android operating system certainly helps bring a degree of cachet as well as functionality. At a discussion with an executive from a downmarket carrier at the CTIA Wireless show in Orlando last week, I asked what customers are asking for as they adopt smartphones. His response: "Android. Android is the brand. They want the apps."

Android support could serve as a sideshow that gives developers less reason to natively support the platform.

But support for Android could also have some potential downsides. With the BlackBerry OS platform generally taking a backseat to other smartphone platforms and a major platform shift to QNX in the works, Android support could serve as a sideshow that gives Android developers even less reason to natively support the platform. Android apps are also unlikely to exploit the PlayBook hardware and user interface, both of which have generated consumer excitement on their own merits. Contrast this with Apple's attempt to optimize the iOS app experience to the point where it sought to block third-party development tools because of concern about cross-platform apps that might pander to the lowest common denominator.

Controlling the software platform may not be as vital to RIM as it is to Apple or others, but it's still an important priority in which RIM is heavily investing. RIM's challenge will be weaving the PlayBook's hodgepodge of sources into a tapestry of engaging functionality. Apple may prioritize a consistently crafted experience but RIM is about delivering what works to encourage adoption and development. The key is ensuring that Android apps remain more or less an option of last resort, while the company can build the case for QNX apps that showcase and differentiate the PlayBook from competitors in the tablet space, and to help the company make a case for the same operating system to power future smartphones.

Scientists improve blue OLED efficiency


Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.

Samsung's 11.6-inch 9 Series laptop official at $1,199, still comes with 64GB SSD

An Italian demonstrator gave us hope, but now we're empty inside -- the exceptionally thin 11.6-inch version of Samsung's 9 Series laptop will indeed come with a puny 64GB solid state drive. Well, perhaps empty is a bit of an exaggeration, as the machine's gorgeous duralumin curves fill our hearts with joy, as does the comparatively inexpensive $1,199 price tag that Sammy just confirmed on its website. And hey, we know of an Engadget editor making do with just 60GB of storage in his notebook, so it's not an untenable thing -- but when Samsung's marketing materials proudly boast that "You'll have room to bring it all with you with the 64GB drive," it's hard to repress the tears. That said, if "portable" is your middle name, you'll find all the pre-orders you need at our source link.

iMobot creeps, crawls, cranes its way into our hearts (video)



It may not look like much, but this little modular robot's got the stuff to give Keepon a run for its money -- oh yeah, and according to its creators, iMobot's got big implications for the field of robotics too. Sporting four degrees of freedom, two rotating joints, and a pair of faceplates that act as wheels, the patent-pending device can crawl, drive, and potentially act as an autonomous camera platform. The surprisingly agile hunk of machinery was developed by two UC Davis professors who say their versatile invention could aid in search and rescue, as well as education and research. We think it's super cool that iMobot could be a hero, but really, we just want to see it bust a move. Check out a video of our new robo love after the break.


Qatar building fleet of remote control 'clouds' for World Cup 2022

When Qatar, an insanely wealthy Arab emirate roughly the size of Connecticut, won the bid to host the 2022 World Cup, one of the stipulations was that its newly constructed open-air soccer stadiums would be air conditioned. Of course, this is Qatar we're talkin' about here, so the solution would have to be as extravagant as its insanely wealthy Arab emirate status implies. That's why it was no huge shock when The Peninsula reported plans to cool at least some of the nine stadiums by using a fleet of solar powered "clouds," designed and constructed by a certain Dr. Saud Abdul Ghani and his team. Dr. Ghani, the head of Mechanical and Industrial Engineering at Qatar University, said that the aircraft (more accurately described as really, really slow drones) will be operated by remote control, made of 100 percent light carbonic materials, and will initially cost half a million dollars each. But, really, what's a few million dollars when it's for a good cause?

Self-strengthening polymer nanocomposite works best under pressure

No one keeps carbon nanotubes down -- especially not these ones. The always popular allotropes have been enlisted by researchers at Rice University to create a composite material that gets stronger under pressure. When combined with polydimethylsiloxane, a rubbery polymer, the tubes form a nanocomposite that exhibits self-strengthening properties also exhibited in bones. During testing, the team found the material increased in stiffness by 12 percent after 3.5 million compressions. Apparently, the crew is stumped on why it reacts this way, but is no less eager to see it working in the real world -- discussion is already underway to use the stuff as artificial cartilage. And here we thought aerogel was cool. Full PR after the break.

Rice University lab creates self-strengthening nanocomposite

Researchers at Rice University have created a synthetic material that gets stronger from repeated stress much like the body strengthens bones and muscles after repeated workouts.

Work by the Rice lab of Pulickel Ajayan, professor in mechanical engineering and materials science and of chemistry, shows the potential of stiffening polymer-based nanocomposites with carbon nanotube fillers. The team reported its discovery this month in the journal ACS Nano.

The trick, it seems, lies in the complex, dynamic interface between nanostructures and polymers in carefully engineered nanocomposite materials.

Brent Carey, a graduate student in Ajayan's lab, found the interesting property while testing the high-cycle fatigue properties of a composite he made by infiltrating a forest of vertically aligned, multiwalled nanotubes with polydimethylsiloxane (PDMS), an inert, rubbery polymer. To his great surprise, repeatedly loading the material didn't seem to damage it at all. In fact, the stress made it stiffer.

Carey, whose research is sponsored by a NASA fellowship, used dynamic mechanical analysis (DMA) to test their material. He found that after an astounding 3.5 million compressions (five per second) over about a week's time, the stiffness of the composite had increased by 12 percent and showed the potential for even further improvement.

"It took a bit of tweaking to get the instrument to do this," Carey said. "DMA generally assumes that your material isn't changing in any permanent way. In the early tests, the software kept telling me, 'I've damaged the sample!' as the stiffness increased. I also had to trick it with an unsolvable program loop to achieve the high number of cycles."

Materials scientists know that metals can strain-harden during repeated deformation, a result of the creation and jamming of defects -- known as dislocations -- in their crystalline lattice. Polymers, which are made of long, repeating chains of atoms, don't behave the same way.

The team is not sure precisely why their synthetic material behaves as it does. "We were able to rule out further cross-linking in the polymer as an explanation," Carey said. "The data shows that there's very little chemical interaction, if any, between the polymer and the nanotubes, and it seems that this fluid interface is evolving during stressing."

"The use of nanomaterials as a filler increases this interfacial area tremendously for the same amount of filler material added," Ajayan said. "Hence, the resulting interfacial effects are amplified as compared with conventional composites.

"For engineered materials, people would love to have a composite like this," he said. "This work shows how nanomaterials in composites can be creatively used."

They also found one other truth about this unique phenomenon: Simply compressing the material didn't change its properties; only dynamic stress -- deforming it again and again -- made it stiffer.

Carey drew an analogy between their material and bones. "As long as you're regularly stressing a bone in the body, it will remain strong," he said. "For example, the bones in the racket arm of a tennis player are denser. Essentially, this is an adaptive effect our body uses to withstand the loads applied to it.

"Our material is similar in the sense that a static load on our composite doesn't cause a change. You have to dynamically stress it in order to improve it."

Cartilage may be a better comparison -- and possibly even a future candidate for nanocomposite replacement. "We can envision this response being attractive for developing artificial cartilage that can respond to the forces being applied to it but remains pliable in areas that are not being stressed," Carey said.

Both researchers noted this is the kind of basic research that asks more questions than it answers. While they can easily measure the material's bulk properties, it's an entirely different story to understand how the polymer and nanotubes interact at the nanoscale.

"People have been trying to address the question of how the polymer layer around a nanoparticle behaves," Ajayan said. "It's a very complicated problem. But fundamentally, it's important if you're an engineer of nanocomposites.

"From that perspective, I think this is a beautiful result. It tells us that it's feasible to engineer interfaces that make the material do unconventional things."

iRig Mic review

There's no shortage of ways to get sound into your iOS device, but one thing has been missing from the field up to this point: a handheld accessory to help you hone your Sammy Hagar (or Anderson Cooper) impression while you're FaceTiming with Gramps. The iRig vocal mic fills that gap, and the included Vocalive app does its part to help you rap over your favorite beat, add sick and twisted FX to your vox, and share your jams with your file-sharing friends. But is the iRig a Napster-level entry into the iMic field? Is it more of an eDonkey, or just kind of a KaZaA? Read on for our impressions of the SM58-feeling cardioid.

The iRig plugs into your pod / pad / phone via the 1/8" jack -- it includes the requisite pass-through jack for monitoring system audio as well. It looks just like any number of Shure knockoffs on the market and feels nice and weighty in the hand. There's also a three-position gain control switch on the body. It feels like a little bit of a joke, though: if we had to name each of the three positions they'd be "almost off," "Big Muff," and "this one goes to 13." And, just for fun, the three settings were backwards on our unit. Also for fun, if you turn it up all the way, you can hear your neighbor's cordless phone conversations.

Which brings us to the first point about the iRig: it doesn't sound good. Remember Your First Sony? Yeah, it's like that. So don't plan on cutting your Rumours of the 22nd century on this thing or anything like that.


But. But! Remember Your First Sony? It was really super-awesome and you probably still pull the tapes out when it's too late at a party to laugh at your 3,000 charming renditions of "Baby Beluga." This is where iRig's paired software comes handily into play: it's called Vocalive, and while its mind-crushingly cheesy title screen might have you LOLing all the way to the Top of the Pops, the quick-and-dirty nature of it lends a Tascam 4-track feel that we haven't really dealt with elsewhere in iLand (except for, oh, the official app).

As soon as the app opens you're free to start setting up your own personal wall of sound: your industry-standard chorus, delay, distortion, compression, and pitch shift homeboys are all here. The increasingly ubiquitous "pitch fix" is also along for the ride, and while it's not quite I Am T-Pain, it's enough to keep you entertained for at least a couple jams' worth of kind of staying in key.


The C60 cassette-inflected recording interface works just as you'd expect it to, but for a price: one track is free, and you can unlock three more for a $4.99 in-app purchase). Swiping between FX, panning, and insert sections is intuitive and feels just like home to us. You can import songs from your library and assign them to tracks in the recorder, which is just what we did here:



We could go on for quite a while about the fun extra features Vocalive packs in, too: a voice trainer that will play scales for you to howl along to, a vocal remover for imported songs that actually functions decently, a looper for extracting killer breakbeats, and a speedtrainer for screwing and chirping those hard-to-handle Steve Vai licks. Unfortunately, we could also go on for a while about just how often Vocalive crashes -- it's not a dealbreaker, but it's certainly enough to interrupt your creative flow. The only way to remedy one of our crashes was a hard reset of the device.


But when it works, man! It really works. Consider the crashes recording breaks, and you'll feel just like a real live studio musician -- the kind of studio musician with only a lo-fi, hi-fun My First Sony at his or her disposal. While we can't whole-heartedly recommend the iRig + Vocalive combo at this moment, when version 2.0 comes out you can be sure we'll be right there with the vocal gain turned to 13 and our pitch fix set to F minus, ready to rock n' scroll.

Apple looking to 'radically improve' iOS Maps experience, may look to you for help

It's tough to read too much into this, but when Apple publishes a couple of job applications hoping to bring on folks who can "radically improve how people interact with maps and location-based services," we can't help but take note. The outfit's currently seeking a pair of full-timers to be labeled as iOS Maps Application Developers, and it's honing in on applicants with "excellent skills in object-oriented software design and programming." We've felt for awhile that Apple's built-in Maps application wasn't even comparable to Google Maps Navigation, but it could be time for that to change. Even now, iOS users need to fork out cash on a legitimate turn-by-turn app if they're hoping to navigate with the iPod touch or iPhone, but we can only hope that these applications are hinting at a more full-fledged internal program for the software's next major iteration.'Course, we're sure TomTom would beg to disagree...

Samsung Galaxy Player 70 captures vision of Android-ruled world in new promo video


It's getting a bit tough to tell Samsung's various Galaxy Players and their changing names apart these days, but the company has found a fairly unique way to drum up attention for its new Galaxy Player 70 model, which looks to be nearly identical to the Galaxy Player 5 being released over here. Mixed into an otherwise bright and cheery new ad are images of what we can only presume is an alternate reality where the Android robot is real, and in charge. Head on past the break to see for yourself.
