In reply to The Lemming:
Not sure what the Xbox is like, guessing its pretty good from some things you see, kindct has worked very well for party games etc, better than ps3 move; move is good but not enough support.
Ps3 has bluray so big selling point, it's got wifi plus Ethernet connection, will play avi/divx etc.
For streaming films from pc to ps3 bit of a pain as need software on pc (think windows media player does it but my pc is old and won't run the required version), otherwise it's not bad, but can always transfer films via USB flash drives, much easier.
It does have 4od, bbc I player, plus other film things, vidzone (free music vids).
Game wise ps3 has some quality games, especially exclusives like uncharted 3, but for 3rd party games (e.g. CoD) are better on Xbox as its easier to code for and because microsoft pay for exclusives (but seems to be to paying to make ps3 version crapper).
