This is now for sale as the
CTL 2GO Convertible Classmate PC, for $549.00. The price will likely go down when it is available from amazon.com etcetera. The 8.9'' LCD, is 1024 x 600.
For general use, I think the Asus EEE tablets may be more ground breaking (not technically, but in price-performance), see
ASUS Eee PC T91 and T101H touchscreen tablet hands-on.
