I loved my Archos, the best thing about it ? You can copy your mp3's OFF the Archos like a hard drive and it uses a tiny unix kernal for the OS player.
No special drivers required.
The downside ? It was bigger then my Creative Labs 30GB drive and the screen cracked if you breathed on it. If the screen held out I would still be running it.
I got the 200 for my son, and I bought the 220 (it has the CF card reader). I also move large files back and forth to work on it. It's great. I'm pretty careful with it, so the screen should be Ok.
