ok.. so first thanks to the people who helped with my mbp or imac and why thread.. I am 99% sure Im starting out with the MBP.. now I was wondering what you guys thought about the 13" vs the 15" MBP.. are the difference that noticeable in the two different versions? From my time playing with them in the apple store it seems at first glance the only real difference in the screen size. What are some things I should know about the 2? battery life etc..? and would I be able to hook it up to a 42" dynex tv? just curious.
