The T91MT has not been announced by Asus itself, but appears to be a Windows 7-equipped version of the T91, which appeared on the manufacturer's website in July. At that time, the Dutch website Asustablet.com, citing "an Asus U.K. representative" as its source, reported that there were to be three different versions of the T91 -- a standard model with a single-touch display and Windows XP, a "T91go" (below left) with GPS, a 3G module, and a digital TV tuner, and a "T91A" (below right), with a multi-touch display and Windows 7.

The T91MT newly unveiled by Amazon seems to be a U.S. version of the T91A, being made available now that Windows 7 is on the market. It offers a folding, 8.9-inch touchscreen display (below) with 1024 x 600 resolution, and employ 1.33GHz Atom Z520 processors. Using the expected SCH US15W companion chip from Intel, the T91MT comes with 1GB of RAM, expandable to 2GB, says Asus.

Compared to the previously released T91 -- which Amazon lists as currently being in stock for approximately $65 less -- the T91MT gains multi-touch capabilities, according to the reseller. The device is also said to offer a 32GB SSD (solid state disk), rather than the T91's combination of a 16GB SSD and bundled 16GB SD memory card.

Featuring a VGA-resolution webcam, the T91MT also comes with other typical netbook amenities, such as 1GB of RAM (expandable to 2GB), two USB 2.0 ports, a VGA port, an Ethernet connector, stereo speakers, and audio jacks.
