Obviously nothing is for sure, but I was wondering besides the rumors about the aspect ratio, is there any mention of bigger sizes for macbooks? Has this ever been entertained in the past, and why is the MB only available in one size? I'm finally going to buy my first mac, and am debating between the MB and MBP. I really don't do any advanced computing, so a MBP might be over kill, but I dont like the smaller screen. Just wondering, thanks!
