It would appear Toshiba (the originator of the classic Libretto small form factor laptop) is looking at the mini-book market.
From PC Authority:
The notebook giant is planning an ultra low-cost portable to join the ranks of the Eee PC and MSI Wind (though not necessarily a direct competitor, they say).
Officials won’t reveal details, yet, but they are showing a prototype of a device they’ve created to spur development ideas. The tiny handheld (shown in the main pic below) reminded us more of a UMPC than a notebook, with the keyboard ditched in favour of a touchscreen keyboard.
For me Windows Vista is not really the best operating system for these internet devices, a bit too much power and as a result poor battery life and lots of heat!
