I have had mine for a 2 months now and am fairly happy with it.
It has a few problems insomuch as it freezes very now and then and requires a reboot (but then it is a Windows platform

).
In terms of connectivity it only has gprs and edge and could do with 3G or HSDPA, but to get these, opt for the Tytn.
The ActivSync that comes with the phone to allow for synchronizing of the phone with Outlook and folders is a bit of a let done down in that it only gives the option of synching either from the pc or from the phone in terms of data so if you make changes on the pc and the phone and want to synch these together, you cannot (Nokia had this function in that you could choose the setting to synch any new data simutaneously from both Outlook and the phone).
