Wow did you see that old laptop in the second link? 2 color monitor and about 3" thick!!
I've thinking about this too, but a simpler approach. I want to find some external tuner that connects to the aux in on my empeg. I would just hide the tuner somewhere "sort of" accessable because I only listen to 1 news channel on the radio and it would be nice to flip to that once in awhile instead 20GB of mp3's.
