I'm looking to buy a new MBP this summer. The only problem is, I'm going to be out of the country on vacation in from July 18th until August 17th. Would it be a smart idea to buy the MBP before I leave or will it be worth the wait? I have to move into my dorm on August 31st. So I have some time after I come back from vacation. I would rather buy it before I go but if there is a chance of getting an update by then, I'd rather wait. Any suggestions?
