Long story short I had to choose between a new Pro or a MB and don't have the luxury of waiting for WWDC. I went with the Pro but I kind of wanted the MB because of how amazingly portably it was. However I am not a power user by any means. I web browse, watch movies, powerpoints, pdfs, etc. I don't do any media work. But at the same time I don't want any of the stuff I do to be slow or laggy by downgrading to a MB. For those who own a MB, how far do you have to push it before you start noticing the slow down? I know it won't be as fast as the Pro but so long as I can do that kind of stuff with no noticeable difference in performance I really don't care. It just bugs me that I bought a computer that is going to be updated in a month when I could have bought one that just got updated.
