These aren't the first touchscreen laptops Toshiba's dished out, but the U500-1EX is the latest, and has some nice specs (4GB of DDR3 RAM, 320GB HDD) for its low price.
At 13.3-inches, the Windows 7 machine has a neat-sounding LifeSpace app from Toshiba, which allows for thumbnail shortcuts on a bulletin board, and a faster way of searching for files with ReelTime.
Internally, it's running on an Intel Core i3-330 processor, 4GB of DDR3 RAM and has the option to upgrade the HDD to 320GB. Bluetooth, two USB ports, HD webcam and mic, the display is a TFT WXGA TruBrite with 1,280 x 800 pixels and altogether, it weighs 2.15kg.
Nothing but UK pricing has been confirmed, but if it's £649 there, a direct conversion would have it at $1,014, but I doubt it'll be that much in the States. [Toshiba release]
UPDATE: It appears to be on sale for $999 at MicroCenter, thanks to Bryan for the tip.
