It's not the same. The S3 uses less battery, and has a bigger battery. It's way faster, has NFC, a bigger resolution, and 0seconds shutter time. Unless you are talking the US-S2, which is not an S2 at all. Anyway: if you have a real S2, it will be sufficient to do all you want (ICS has been around for over 1 or 2 months ;-) ). But then again, a HTC-G1 also does the things I need to do with a phone. (None of which is actually calling, since as a real Nerd I prevent any cell-phone calls). Buying an S3 is a question of (very practical) luxury.
