I am in the market for a MBP. I know I want the 15" but I am not sure which model. With the education discount, I can get the baseline for around $2100 (with an upgraded HD to 160GB). Or, I can get the better 15" for around $400 dollars more. Here are my interests: 1) Computer/Mechanical/Electricial engineering 2) iMovie 3) Garage Band 4) Windows for playing games one would find on PS2 or Xbox 360 (Madden NFL 2007, Spiderman, Call of Duty 3, etc.) Finally, I might be using Final Cut express HD. This is only a possibility and if it did happen, it would not be used real often. Also, with the games, I would only be playing from time to time, but I do want quality graphics. Since I will have to purchase Windows (a good sum of money), I don't have a whole lot of money to spend. If the upgraded graphics card and boosted speed is worth it, then I will come up with the extra money somehow; otherwise, the baseline. Thanks for any help!
