Hi, power wise/small screen the macbook air didn't cut it and I've decided to go back to a MBP. i was hoping some of you could give me some input so I can make the correct choice. I'm contemplating getting the Unibody 2.66 GHz model for 2199 + tax (Using ADC discount). or the refurbished 2.5 GHz MBP for $1599 + tax. It's going to be my all purpose work laptop running scientific programs, wireshark, and huge excel sheeets, managing databases. Will be traveling often with it. This laptop should last me 3 years. I like the keyboard on the unibody and the better build quality but am unsure about the glossy screen. I like the early 2008 MBP because of it's great price and the fact that it's a proven performer i.e. not rev A.
