I had an iphone from the start till the 4. The wife and I switched to the S3. The only things I miss or dont like is lack of a facetime style app, strange battery life and the speaker is on the back of the phone. Otherwise I think the s3 is supperior in every way.
The battery life I have to talk about. Some days I can use it, listen to pandora and still have battery end of day. Some days I can be out and about, barely use it, and it be dead by 3pm. Also mine is quirky about GPS. If I go somewhere (like work) where I lose all cell/gps signal I will have to restart my phone before I can use gps. My wifes s3 doesnt do that
