"Hate" sounds hard but poor Coverage is an argument.
Personaly it's a good option that T-Mobile got modern GSM/GPRS-Networks in the USA, too.
Hopefully the coverage got better.
Here in Germany we never could understand why you used pagers etc. so long in american cellular-networks as SMS- and Paging-Functionality works on our networks for at least 10years. So you got Messages direct to the phone and not to any crappy pager
Actually I got a blackberry and it's a simple but lovely device (6230) perhaps I'm gonna buy the 7290, too because of blueooth functionality.
My communicator 9500 from Nokia got everything I want and need but it has a camera...
