I no longer need a laptop since I have a work computer so I'm looking to sell my MBP and get a mini to use a long side my iPad. I'm looking at the refurbs right now and can't decide which model to go with. I could get this one with what I think is a faster graphics card and slightly slower processor. http://store.apple.com/us/product/F...53d553105c8ce999c536a06ed7bad4175152951f4c2d9 or this one with a faster processor and slightly worse graphics card. http://store.apple.com/us/product/FD388LL/A/refurbished-mac-mini-23ghz-quad-core-intel-core-i7 A little background. I'm comfortable doing HD and RAM upgrades so that's not really in consideration. I'm just looking at the stuff I can't change. Thoughts?
