Opinions of my new SGS2 so far.
Awesome
Massively customisable, still haven't found a setup I like yet though, may take a week or two. Taking suggestions for launchers
I love how it is so sleek and thin compared to the iPhone. The screen, although not as crisp is much more vivid in colour. The extra screensize is nice too, it made the iPhone look tiny after I'd used the SGS2 for a bit, however all in all iPhone screen wins slightly. The iPhone screen really should have been made bigger in the 4s tbh.
Main criticism, is with Kies... on first impressions, it seems awful. In fact PC connectivity in general could have been nicer.
