I'm not sure why, but I got a white iPhone rather than a black one and would rather have a White Xperia Play, which is exclusive to o2 in the UK. I think the white casing makes it look a bit smaller than it really is.
Just need to wait until some sort of firm pricing deal is up... my iPhone contact expires in December, so not too long to wait. As I've already seen lots of posts stating that formerly touchscreen games are a lot better with proper controls, bring it on!
*Until about after a week of use!
