Nokia N800 Tablet PDA
The Nokia N800 Internet Tablet is a powerful Linux handheld computer capable of playing transcoded movies and TV shows on its beautiful 4.1" 800x480 screen. It has a stand and speakers for two people to watch at once, or you can plug in headphones. You can shrink a one hour program into 180 - 250 meg and it looks great. You can fit about 4 hours of content on a 2 gig SD card which are pretty cheap these days. You can set up MythTV to automatcially transcode and copy programs overnight to an SD card so you can watch on the train or bus in the morning. It's a lot lighter and more portable than a laptop, has a larger and nicer screen than an ipod, and because it's Linux, open source developers are porting and writing new Linux apps for it.
You need to have the latest image from Nokia to have a stable media player. You can use the Windows software provided to install the image or follow these easy Linux instructions:
