ok this is not really a phone, rather more of a three devices in one. I have this for over six months now and can't live without it. Especially if I am on the road and do not have internet connection. I can check email, calendar etc...It will be great to have bluetooth working. Supposedly that is in the making. Also since a newer treo (650 ?) is coming in few months, this older model will probably be sold much cheaper than now. So you may want to hang tight for a couple of more months.The reason, I am giving it 4 stars instead of 5 is because I have had some hardware problem and recently my original unit stopped working as a phone. But sprint was very prompt and sent me another unit. So not much to complain there. :-)**Update: Treo 650 is out now. It seems to have lots of things that I desired in 600. So hold on to your monery for that ***
