Ohhh you really wanted an Ultrabook? Then you probably went right with the Macbook.. xD
Although I'd say a decent gaming Alienware would be just as good, you're right - those Apple trackpads just can't be beat. Is it the Retina Display screen? :3
Why did you buy a Macbook Air if you were just going to install windows 7? 'Cos you could've gotten easily yourself a 512GB SSD, 3.0GHz+ Core i7, 8GB of RAM, and a darn sexy GPU in a non-Apple laptop for a lot less than a MBA..
