Dell Axim Carputer w/video
 

There is some seriously cool things happening with this setup

Click me -- make sure to watch the video

The only real downsides i can see is the stability of the Windows Mobile 5 OS blows chunks..
and the processing power isn't as great as a dedicated carputer..
*Edit* I almost forgot -- The sound quality blows chunks as well.

I'm not planning on doing this but i thought it was cool..
what do you guys think?
