My thoughts are:
the borders (esp top) are too big.
width and thickness are good.
but overall its a bit long.

im not sure on the power of the processor, but it doesnt look like its caught up to its competitors.

comparing to S3:
- battery isnt as good (rated 8hrs talk as opposed to 12hrs on 3g)
- the screen is a weird res (640x1136 as opposed to 720x1280) but not bad for 4"
- only supports memory card up to 32gb as opposed to 64gb

But, does any of that really matter? the sheep will flock, and it will be more popular with women because of its slightly smaller size compared to the samsung's or htc's
