I have not had the problems that Pharma has but I can tell you that my 7100t, while cool, can be quite frustrating:
1-Needs to be rebooted (maybe you old school blackberry folks are used to this) and sometimes won't place calls until it gets rebooted. AND, you have to yank the battery to do it. AND it takes minutes to reboot.
2-Painfully slow dialing
3-Not really happy with ANY of the themes
4-Battery life sucks
But D@#n is that email thing cool. I guess it's a love/hate relationship.
