If I were to add a point, my S3 is plenty roomy enough for me to enjoy typing on it. I was apprehensive about losing my physical keyboard (I also upgraded from a Droid 2), but I don't regret the change at all. This big screen really is a luxury. The iPhone on the other hand may be too cramped for typing on screen, unless you have delicate lady fingers (I have the absolute manliest Italian sausage hands). Like another poster said, go play with some phones. That might make your decision a LOT easier.
