Blackberry = no-no.
Although they are "the email phone" they are lacking in vital features such as WiFi, and keypads are all disgusting.
WiFi on mine and a QWERTY keyboard... I havent got the smallest fingers, but have no issues using mine.
iPhone pushing things further? To me they have only just caught up. Can you send MMS (Picture Messaging) yet without an added application?
Personally I thought about one.. but I opted for the Blackberry.
