I still have the last 2009 model. My MBP is about 6 months old. My job is full-time web-development so it makes sense to always have the cream of the crop. My usual cycle is just to buy a new stock MBP every 8 months. This way I never have to buy apple care as well. This is the first time I've been considering upgrading the HD because of SSD. I also have another incentive now: more memory and higher resolution. If I buy a new MBP it would be the i5 or i7 with 8 gigs of memory and 256 SSD. It'll cost me about 3 grand. I could sell the MBP I have now for $1,300. Am I crazy or should I do it? The thing I'm worried about is I won't be able to sell my more expensive MBP when the time comes around when I want to upgrade again (probably within a year or two).
