Long time lurker, first time poster. I own a top of the line anti glare 15" macbook pro. One of the things I was never a fan of was the weight. I love the power it offers but treking across the university compus aint fun with this and books. I'm considering selling this and putting that towards a retina macbook. One of the reasons i like it was it was a powerful notebook but is also thinner. A big factor in my decision is if its that much lighter than the regular macbook. Is it that much lighter? I think im gonna sell my 2011 macbook pro 15" for 1650. its 2.0ghz i7 quad core, 4gb ram, upgrade intel 520 series 120 SSD, anti glare high res plus accesories, speck hard shell, moshi palmgaurd/cleargaurd covers . The computer is MINT and can pass as brand new aestecically. do you guys think thats a good price? Anyways those are my 2 questions. Thanks!
