I expect near-enough everyone has heard of Asus's Eee PC, and if not, welcome to the world above the rock, but what you probably haven't heard of is SplashTop Linux, first débuted on the Asus P5E3 Deluxe motherboard. To recap, it is basically a very lightweight Linux OS licensed by Asus, which aims to provide basic functionality such as Pidgin instant messenger, Skype and Firefox without the need to load the full OS - the idea being you can get to important programs quickly.
Now on the standard spec, the Eee PC SplashTop is probably - scratch that, definitely - a bit moot because the normal Linux OS on the machine is so fast to load anyway, but with a forthcoming Windows version the appeal of still having a fast loading web browser will likely be very present. No official word from Asus on this one though, so keep your eyes peeled people.
If Linux doesn't float your boat, then how about the spotting of a slightly upgraded model of the Eee PC sporting an enlarged 8in screen, leading to the removal of the rather unsightly black edging on LCD in the current model - check the photo to see what I mean in more detail. Other than that that change, and the moving of the speakers to accommodate it, everything else is exactly the same, including the screens resolution of 800 x 480 pixels which means the OS will still look exactly the same. In fact, calling this change an upgrade is a bit of a misnomer; refresh is probably a better word - although usability should be a bit better for most people which makes it worthwhile.
