I'm an attorney who has had this phone for almost one year (June 2007) and I'm ready to get rid of it. It does not play well with others. I had a palm for years which synced my calendar/to dos, etc. with my office. When palm switched to microsoft, the calendar only syncs from the desktop - all data entered on the phone is lost -- all the techs have said that I have to live with this -- not very realistic. It will not sync with my contacts list. It crashes about once or twice each week. My first one was completely broken when sent to me and the replacement has not been much better. It will suddenly not ring so I have missed calls and messages. The battery does not last long (I've turned off the email checking feature - when that was on, I received 3-4 hours of use, with it off, it must be recharged every 2 days -- if you forget and the noises are off to alert you to a low battery - you really lose!) Bottom line is that this is an extremely unsatisfactory "smart" device for the money. The unreliability and inability to work with others cancels out the features I liked (GSM) (PDFs that you can carry with you).
