A major trade-off no doubt. My iPhone 5 doesn't give me any problems with size, but it's utility is probably much less than a Plus (can't be sure about this though)
But we all knew this was going to happen. All the returns are expected as no one can blame you for changing your mind, and in this 'very particular' case, changing your mind more than once is probably normal.
I say "In this particular case", as some of the waffling in these forums is beyond belief.
note: I haven't received mine yet, but when I saw one in the Apple store I knew I was going to get one. I also knew that I wasn't sure what it would be like in everyday use. Apple has made this thing, and can't expect any of us to know WTF we are doing. I even owned a huge Samsung Note and I still don't know as I returned that because it was Android and NOT because of the size ( size wasn't really a problem, most of the time that is)
Actually, i'm posting this as i'm just a confused as any of you
