ASUS has put their Eee PC T91 onto their US website now. unfortunately, there is no certainty about when it will be ready for the public, and no detail US$ pricing until now.
ASUS Eee PC T91 is one of the coolest convertible netbook tablet so far. It has a 8.9-inch touchscreen, powered by Intel’s Z520 1.33GHz Atom Processor. Although it’s not as strong as Sony VAIO P series with Z550 Atom processor, ASUS has an excellent “Super Hybrid Engine” to boost battery life up to 5 hours (Sony can’t do this yet).
It has 1GB of RAM and 16GB SSD Storage. Pretty minimum, but enough to run XP and several applications installed. ASUS Eee PC T91 also has optional HSDPA cellular connectivity, WiFi, bluetooth, TV tuner and GPS receiver.
Although there is no pricing yet, Slipperybrick estimated it should be around $684 because on the UK site, the price for ASUS Eee PC t91 is £449.
