For those that are having second thoughts about this notebook, I want to say that you'll love it, go for it withouth thinking. Mine is dead silent, does not whines, does not moos (at leats not now) and they don't get that hot as many people say. You can use it in your lap while surfing the web with no problem (even in shorts). Let's say it's just warm. I got a black one, it looks nice, very nice. This is my first Mac, so I am getting used to many things of OS X, but I hope to continue with this happy beggining. Wish me luck. Kind of useless post, I know, but just wanted to say how happy I am with this notebook.
