hi guys, I've just ordered my first macbook yesterday. its a 11" MBA 4gb, 64 ssd. I didn't really want to spend another $200 for 64gb but I'm starting to regret it now. this will serve as my travel notebook/ second computer around the house. I'm a big fan of Apple products but this will be for work travel so have no need for OSX, is there a way I can just have windows 7 on it to save space? I've been looking around but could not find anything. thanks
