Hi, I can't decide what to do and could use a few objective opinions. I currently have a mid-2009 13" MBP, 2.53/8g/500g 7200 hdd, superdrive. Installed Lion on it, I really have no complaints. A friend offered to buy my machine for $800-900. I have a 120gSSD from OWC on the way. My original plan was to put the SSD into my current MBP and be happy for another few years. But it sure is tempting to sell my machine, get a new 13" MBP and put the SSD into it. I would keep my 500 hdd and add it via optibay, and put the 750hdd that comes in the new machine into my old MBP for my friend. New price through MacMall - $1420ish Sell my current MBP - 900 Is it worth the upgrade for $500? Mine is a core 2 duo machine. I'm leaning towards keeping mine, but if the performance were that much greater to warrant the $500, I'd go for it. I would appreciate your opinion! Thank you.
