It's cool they're using Android now. I had one of the Archos AV300 range devices when they first came out (6 or 7 years ago?), which used their own proprietary OS which was fairly rubbish. I r/e'd most of the hardware, firmware format, encryption etc which was a heap of fun.
The founder of Archos emailed me to say he'd be suing me unless I stopped. Good times, good times :)
FWIW, unless they've drastically changed I thought Archos hardware was fairly cheap and ill thought out. Didn't seem anywhere near the quality of say Samsung or Apple.
