If you're asking, then you probably don't need one now and can wait.
Don't wait just because it will be "better". There is always something better around the corner, and the difference between the late 2011 model and the 2012 model won't be much to wait on.
well if the new pro comes out in 2 months i gonna hate myself. but if it comes out in 6 months or so. then i don't care.I currently own a white MacBook 5,2 that is slow. I really want a new one but the fear is what the next version will have and when it comes. I would hate to buy one and then in 2 months a new one comes out. Decisions, decisions, decisions.
