Hi Everybody, I am on the verge of purchasing a Macbook Pro, but I am very new to the Mac world and in need of some insight. I am debating between the 13-inch and the 15-inch models. In comparing the specs between the models; aside from the obvious differences such as the processor, price, and screen size, are there any other significant differences to be aware of? I noticed that the specs list the 15-inch model with Intel HD Graphics but the 13-inch didn't have that listed. Would I still be able to connect the 13inch model to an exteral LCD tv and acheive the same results as a 15-inh model? Any information is appreciated.
