Hi, I am going to buy my first Mac Computer and I have decided to go with a new 2009 Unibody MBP. This is going to mostly stay on my desk at home but I will be taking it around to places I need it so thats why i went with the MBP instead of a MacPro. Anyways i was wondering if you guys think i should go with the 17 inch or the 15 inch. I have heard things about the 17 inch like its too heavy and its very cumbersome. Whats your opinion?
