Adding a messenger to xbox isn't going to 'over heat' it. If your a dumb @$$ and you put your xbox in a enclosed space with half an inch all around and think its going to cool then no wonder it over heats. I can't find a PS3 in any store that isn't turned off because of heat yet I can still use the 360. And the whole messaging thing while playing games, you can change that so it doesn't pop up while your watching movies or playing games.
Well its good that they have 1,600 different things that they are updating. Not just the addition of Messenger and the Marketplace blade. Their also making the network 3 times faster:D...The keyboard is a nice addition. I imagine it will be roughly $30-$40. Which isn't that much to ask. Everyone cries about buying additions to their Xbox 360, but its not like you have to...for example the HD-DVD drive. Only buy that if your into HD movies and have a good enough setup for it. Microsoft isn't forcing you to buy their accessories, thats something that you've had to make a decision on. Good work Microsoft, doing a lot better then sony is.
