UMPCs, he said, will eventually splinter into a range of ultra mobile, ultra tiny devices. By June of this year, these devices will be 75% smaller and 50% more power-efficient than what’s on the market today. Next year, the "platform will be one-seventh the size of current devices and use one-tenth the power." Exactly what kinds of "Ultra Mobile devices" (UMD? Does Sony know?) we can expect to see is unclear, but the Apple iPhone was cited as, at the least, a decent execution of Intel’s "mobile personal Internet" vision.
What about UMPCs and handtops? They already provide a very full, very rich online experience that I would call both mobile and personal. Wouldn’t you?
