Aluminium or not, the 9400M is not cut out to run games satisfactorily in my books. I have accepted that fact when I moved to a Mac. Nobody knows what the minimum requirements are to to run these two games you mentioned, and even if they are revealed, you dont want to be running them AT minimum requirement with details turned down and resolutions dropped way low. The enjoyment of a game diminishes , to me at least, when the eye-candy gratification is chipped away little by little, to make the game run acceptably.

No offense and I myself am an avid Apple supporter, but those statement on plasticky PC laptops apply to lwer entry level laptops, not the higher end models. Apple have always made their Macbooks as higher end models, hence the build quality. As for popups with Vista, it becomes a more stomachable experience once you've tweaked it properly, and I agree if you say that a user should not have to tweak their laptops in order to get it going off right out of the box.

I myself am getting the Macbook Air 1.83Ghz most probably next week, I just hope their issues the horizontal lines + no 4 finger swipe is resolved before I finally make my purchase.
