I'm too cheap to buy a mac at retail lol. So, I'm looking for a laptop, more specifically a used mac. My question is that, is it wise to plunk down close to $600 for obsolete hardware? i.e. Macbook Pro C2D 2.4Ghz when a Core i5 or i7 series laptop can be had for under $600? What should I pay for a decent Macbook/Pro that will run Mavericks?
