I have the opportunity to purchase a (well taken-care-of) 13" Macbook Pro (Mid 2009) for $500. I'm an iOS developer, so I would be running Xcode and other dev tools. Specs are as follows: - 13" display - No dents, etc. - 2.53 GHz Intel Core 2 Duo - 4 GB 1067 MHz DDR3 - Battery has had 174 cycles, normal condition - NVIDIA GeForce 9400M (256 MB)disc - 250 GB HD Is it a good deal? Will it run Xcode without problems and have enough screen real estate to not drive me crazy?
