Think of the Ubuntu Edge ($830) as a proving ground for next-generation mobile technology — most of the things you see here will likely make their way onto big-name handsets. The biggest of those technologies is convergence: hardware and software that seamlessly transitions between desktop and mobile. All you need to do to use it as a desktop PC is plug it into a display using HDMI, and pair it with a bluetooth keyboard and mouse. This is possible thanks to a fast multi-core CPU, 4 gigs of RAM, and a 128 gig flash drive. Other impressive features include the ability to dual-boot between Android and Ubuntu OS, a 4.5-inch sapphire crystal display, stereo speakers, and two LTE antennae.
