Hi, I have decided to buy a Macbook pro and am torn between the 15" and 17" i7 AG models. Will be using the laptop mainly for programming, casual gaming, and some light photo and music editing - only have 6 months more of uni so portability is not essential Need help on the following : -How much more screen real-estate does the 17" have than the hires 15" ? -Is there a performance or battery life difference between the two? ( real world battery life experiences would be appreciated) -Any differences in the comfort levels when typing? (I couldnt test out using the laptops on my lap in the store) I have been able to compare the base glossy models in a local retailer and 17" screen is just amazing!
