New Sony Vaio...full-size power in less than a pound

Sony released details of their new Vaio UX computer today.  While it won’t be released until July, it appears you get a lot of functionality in a package that’s less than a pound. On the other hand, it’s not a UMPC/Origami device.  You do get:

• Core Solo processor, 1.2 ghz ultra low voltage
• Slide out qwerty keyboard
• 512mb ram ( not upgradeable )
• 4.5” SVGA (800 X 600) xbrite screen
• equipped with stylus for touch
• biometric sensor
• 30 GB Hard drive
• two built-in cameras
  • one on front for video
  • one on back for taking pictures (1.3 MP)
• WWAN (Edge), wi-fi, and bluetooth
• Battery life: 3 hours
• Docking station support
• Weight: 1.2 lbs
• Windows XP Pro

With no Windows XP Tablet Edition it  won’t work as a tablet.  I think this is a mistake.  Sony had a lot of experience building the U-70, which also had a passive digitizer. How did they miss the boat on this one?
