As cell phones begin getting bigger and bigger again, it begs the question what is too big. I know people have discussed this (tirelessly), but lets get a straw poll going to see what the general consensus is. So what is the largest desirable screen size for YOU (not necessarily the largest you would ever buy). What I mean by that is if 3.5 in (current iphone) is the largest desirable size for me, and the next iPhone became only available in 4.0 in, I would still get it because the other benefits would outweigh the size disadvantage. But what is the largest you would possibly want your screen size to be on a phone, before it starts becoming too big/cumbersome to not have added benefits.
