Elonex One-t ?
I got an Elonex One-t for my Xmas. I initially ordered the basic Elonex One for £99 back in August or thereabouts, and they offered me the better-spec'ed One-t for the same price. It didn't actually arrive until early December, but I was in no hurry for it, as I was buying it as a hi-tech toy, not a 'second computer'.
I've found it to be a pretty amazing little machine, actually. It's not the most powerful processor in the world, but the display is bright and sharp and the keyboard and mousepad are positive and decently-sized. You get 2-3 hours' worth of useage from a charge and providing you downgrade frame rate/bit rate/resolution, you can play movies for keeping the kids occupied in the car, etc. It can't hack Flash Video, so YouTube et al are not an option, but you can play most Flash animations and Flash games. (Strongbad E-Mails, YetiSports for example).
There are some great (native code) games, apps and hints and tips on http://www.littlelinuxlaptop.com/ and there are quite a few unofficial communities springing up around it. Hell, some people are even developing their own lean-and-mean operating system:
Big thumbs-up from me !
