mjb:jeffnz: I actually wasn't going to use a case as never did on S2 but was in PBtexh yesterday and they had the Rock case quicksand available. Looked and felt good so bought one thus far pretty impressed. Bit expensive at over $40
I was the same to be honest - the S2 was a little more textured though, so never really felt that I was going to drop it. the S3 is a little more slippery though for some reason. Also, with the curved S3 screen, if it's face down the glass touches whatever surface you put it on.
I would have liked to try one of the Rock cases to be honest, but again, couldn't find any around town.
Where about are you in NZ? I have a Rock case and it is very good quality. If you in Hamilton then you can trail my brand new Rock case :)
I'm still waiting for my S3 so I have no use for the case at the moment. It is just sitting on my office desk along with my other cases and 64GB card and 8 screen protectors.
