This does not really classify as a computer but it is something that I have found to be worthy of enough to be on this page. The SEGA Nomad is a handheld 16-bit Sega Genesis game system. It has a built in color screen and plays standard sega genesis cartridges. It has excellent picture, sound quality, and speed. It can be hooked to a TV also and you can plug normal sega genesis controllers into it too so it is just as good as a normal sega genesis. I'm not too much into video game and console stuff but a friend knew I was interested in it and got a pawn shop to throw this unit in for free when he purchased some guitars. I have documentation for it so if you have any questions just e-mail me and I'll look it up for you.
