PDA Buyer's Guide
reviews the Sony VAIO U50/U70, the hybrid PC/PDA that has beaten both the FlipStart and OQO to market.
They like the fact that it has a touch screen that works with any PDA stylus, is incredibly small and portable yet runs Windows XP, has VGA, USB 2.0, Firewire ports, wired Ethernet (802.11g), a Memory Stick slot, and a CF slot.
They don't like the price. $2199 (U50) and $2699 (U70).
Only one question: Why should it be necessary or any beneficial for a small device such as the U50/U70 to run Windows XP? Long-boot times are not very convenient for an "on-the-go" device like this one...
