So posted previously on the issues I've had with my MBP: http://forums.macrumors.com/showthread.php?t=817733. Apple won't replace as it's a refurb and they'll only exchange if they have the same model, which they don't. They have advised however they'll collect and refund what I paid (£1150). So question is do I pay the extra and get the 2.66GHZ model, go with a 13" model or go for a Windows lappy? Anyone gone from a 2.4GHZ 15" Unibody to a 13"? If so how did you find the change?
