Folks at Pocketnow have compared the boot up (startup) time of iPhone 4 (running iOS 4) with HTC HD2 andNexus One (running Android 2.2) and LG Panther (running a beta version of Windows Phone 7).
Since I hardly restart my iPhone, I must admit that I had never paid attention to boot up time until I watched the video comparing the boot up times of the iPhone with other smartphones.
