Hey guys, I've got the itch to buy something again, and I'm not sure what will suit me best. I have a gaming desktop, and a Thinkpad W520, but I want something that is more sleek, and easier to use around campus. I was originally thinking the 11" MBA, but I recently found a good deal on a 2011 13" Pro, and I am not sure what I should do. I like the fact that I can upgrade the ram and HDD in the pro, but I'm not sure if the added weight will be worth it. What do you guys think? Thanks!
