At first I really liked the Q. I was using the Treo 700W because of its compatibility with corporate outlook and the Q has that same compatibility but in sleek, slim package.But then the battery problem became painfully apparent. It would not even last a whole work day with around 90 minutes of phone calls and auto synch set for 15 minutes. So I trotted down to Verizon to get the extended battery. This worked, but now the phone was so bulky that I was better off with the Treo.So I returned the Q and reactived the 700W (which is not great on battery life but far better than the Q).I would keep the Q were it not for the battery life issue. It is less fully functional but I think overall a better package than the 700W. If you only need to have it check your e-mail every few hours, and you do not make many phone calls, this is a great choice. But until the battery issue is sorted it is hopeless.
