Hi all, This is my first post so excuse me if I appear a tad rookie. I was looking into buying a cheaper older MacBook pro as my budget can't stretch to their current retail price and I came across a used one for £499. It's the 13" A1278 model with 3GB Ram and 160GB HD. October 2008 I think Firstly is it worth that much ? and secondly, how will it perform while running mountain lion, will it be a slouch? Here are the full specs http://www.everymac.com/systems/apple/macbook/specs/macbook-core-2-duo-2.0-aluminum-13-late-2008-unibody-specs.html Would really appriciate a response!
