This must be the question that many people will ask. Will you upgrade your Samsung GALAXY S II to the latest Samsung GALAXY S III? Pocketnow has done a fantastic job of comparing both side by side.
What do you think? In my opinion, having a quadcore processor is great but not many apps utilize the quadcore. So, what you get might be similar (in terms of speed) for both devices.
However, I have to say that Samsung has done some innovation on the software which makes GALAXY S III different from S II. Check out the video.
