I'm thinking of purchasing a Macbook 2010 in good condition of course . I'm thinking of upgrading it to 8gb and keep the 250 HDD, also putting Mavericks on it. I usually go on the web most of the time like youtube and write papers, and was wondering if this is a good laptop for high school? The only heavy thing I'll do on it is maybe gimp and WoW. Also, should I purchase this 2010 macbook, 2008 Macbook air, or Aluminum Macbook 2008 w/ the same specs? It's my first mac ever since my iBook g4 broke, and I hated that slow thing. Thank you very much!
