So, the answer is no, you haven't owned one, put one in your pocket or used one as a daily device. You saw and touched a few in store and balked at the size without attempting to see if it's useful. That puts you in a poor position to dismiss the larger handsets as bad designs and criticize their usability.
What are you talking about? You're not even making sense. My iPad is useful, but I sure don't carry that around with me everywhere I go. I very clearly stated that the larger phones do not fit in the pocket I want them to go in. I never once mentioned "bad designs" or "usability" - simply put, if it's too big, it's not coming with me. End of story.
I have my keys in one pocket and money clip & credit cards in the other. The phone goes in the "other" pocket so it doesn't get scratched. And no I don't want to combine the items because that will be too much in one pocket.
I've been using the same setup for many years, so don't act like you know what's best for everybody. The iPhone 4 (and my previous phones) fit perfectly in the 5th pocket. Anything bigger will not, which means I will not buy. Why is that so hard for you to grasp?
