Archos 20gb MP3 Player Questions

[jimmyl930]

I'm considering the Archos 20 GB USB 2.0 MP3 Jukebox Recorder.

- How is the Rockbox OS? Can I still backup the original firmware?

- The battery life is officially 10 hours. Is this accurate?

- How does walking affect the music playback? Is this bad on HD mp3 players?

- Is it easy to replace the batteries?

- How good is the sound recorder?

Thanks.
