I have been using this device for 8 months and been pretty happy with it. As with all phones and PDA's it has it quirks. The biggest one being that it occasionally locks up and there is no rhyme or reason to why and sometimes takes 20 minutes to get the thing reset and back up and working. It is not something that happens all the time but it does happen.On the pluses, syncing with my corporate mail, calanders and contacts without any effort on my part. I love this seemless integration.On the negetive,it is hard to dail numbers while doing something else, like driving.Jury's still out on the perdictive typing. And with large fingers, sometimes I may cause my own issues.Overall, I like the device and am going purchase one for my wife who has email envy...
