What do you guys think about this system of upgrading... Buy a Mac, sell it next year to pay for the upgraded model and doing it all over again every year. How much would I be spending every year towards the cost of a new Mac minus the resell value of my old Mac? $1000 more or less? I'll definitely keep the Mac in mint condition if that helps. If I'm going to buy a Mac it would be the i7 iMac and upgrade from there. Here's a little context: I'm entertaining the idea of building a Hackintosh so I could upgrade one or two components every year instead of buying a brand new Mac. But stability and high maintenance is making me have second thoughts (I use ProApps). I also game so periodically upgrading video cards is a ritual.
