I picked up a 2009 Macbook for $100. It has 2gb of RAM, and a 120gb HDD. I upgraded it to Mavericks - which is a RAM hog. It's not good for my uses. I'm not sure if I want to update it to 4gb of RAM to make it usable, and maybe add an SSD (and keep it for giggles), or just sell it. Does anyone have any experience with the early 2009 Macbook, especially with how it handles if you upgrade it? Or should I just pop snow leopard back on it?
