Had a go on one of these in game, very snappy and inuative menu system, uncharted 3 looked sublime, tried wipeout also, although it was graphically good, it didnt captivate me as much as I thought it would - but then the ps3 version of the game wasnt something I was interested in (uncharted was a different story though).
Lovely looking machine, bit more chunkier in the hands but perfect size for me.
And the analogue sticks/dpad/buttons - spot on Sony.
My only gripe, I think its probably not worth around £220 at this stage for me. So I may hold out a few months and see where the pricing will go, I am sure we will see price drops similar to how the 3DS droped in price over the course of the first 6-12 moths.
(I'm sure come release day that logic will go out the window

)
