I think after I sell my 17" mbp I'm going back to a mac pro, at least the gpu is user replaceable...
Honestly guy...relax. Talk of selling your mac is a little premature at this point. You are really adding to this snowballing hysteria going on this forum with all your worrying in multiple threads!
If there is a problem then Apple will address and deal with it...or else you and I and countless other loyal customers will be breaking the doors down at every Apple store in the country....and you can take that to the bank.
