Why XP Home?

Averatec touts 3G, Wi-Fi UMPC: "Notebook specialist Averatec will ship its take on the ultra-mobile PC concept this autumn, offering a handheld Windows XP Home Edition-based machine with a keyboard that sits underneath a slide-out 5in, 1,280 x 1,204 touch-sensitive screen."

I think its a waste to ship it with XP home. Most people that would spend money on such a small PC would be power users (don't think mom and pop would spend a grand on a UMPC). Give that, why not out WinXP Pro on it? Come on Averatec, think!
