Hello, I am currently looking at buying a Macbook and would appreciate opinions about this. I'm looking at two options. A refurbished Macbook, 2 GB with 250 GB of memory or since I'm a student I get an education discount buying a brand new Macbook with 4 GB processor and a 320 GB of memory. I know that 250 GB of memory is plenty for my uses. But the price difference is only $139 so it kind of seems worth it. What do you guys think? Thanks!
