I'm about to get a new one. Not an iPhone -- I have better things to do with $600. I am, however, looking to replace my Audiovox XV-6600 and its Windows Mobile with something Linux compatible.
I almost went with the Treo two years ago, when I bought this one, but kept hearing of problems with hearing the caller on the other end. Having used a phone for the last two years that requires near-complete silence to be able to use effectively, I am fully paranoid about the matter now.
Are there any suggestions for PDAPhones which are compatible with Linux (for syncing contacts, appointments, etc.) and at the very least, provide minimally acceptable call quality (that is, at least comparable to one of the low-end "free" phones)? My wife has one of those freebies, and it rocks compared to the tinny crap I try to listen to when I use my phone.
