Does anyone hare have an Android based phone and use it with Linux on their desktop?
Chris,
Depends on what you mean by use it with Linux. I got the second-ish Android phone that came out from HTC - the Magic. It's running Android 1.6 and I've been using it for 18 months+. It syncs directly to Google for mail/calendar/contacts. I've installed apps, media and other stuff directly on to the card using a suitable card reader on my laptop and desktop linux PCs.
Other than that, I haven't had much need to connect the phone directly to the PC. What use cases are you interested in?
Peter.
