When someone doesn't list any reasons, I just assume he couldn't live up to the expectations of the device.
Yeah, the OP should provide specifics. I can't be the only one who takes the time to do that. If you cannot fathom how the S2 doesn't blow the iPad4 out of the water, consider yourself lucky. LOLseriously! the OP seems to blowing smoke! cannot FATHOM how the S2 didn't blow the ipad out of the water! tsk!
