I was going to wait for the iPhone 5 before purchasing the SGS III; however, I had to pick one a couple months ago to keep my unlimited data plan.

I compared the "older" iPhone 4s, HTC One X, and this one. Overall, the features convinced me to go with the SGS III (I had to go by reviews from international owners). I got the pebble blue 32GB and got my wife the white 16GB. The size is no issue for me or my wife who has smaller hands than the average woman her size but it didn't really matter since she uses both hands all the time.

The battery life for me is not as good as I would have liked (Wi-Fi and LTE on always) given the size of the battery. It lasts for two-three days at home but doesn't last 7 hours at work. I think it's because the materials/layout of the building I work in as all my cell phones got worse battery life/reception but this one gets a little worse than the others I've had. It's probably due to the phone trying to get the LTE connection all the time. I'm too lazy to go 3G only so I just recharge it at work.
