If I were to get a Mac, I was thinking of either the 13.3" Macbook or the 15" Macbook Pro -- but there really aren't a lot of functions that the Pro has that I need (I just like the bigger screen options XD). What kind of functions does it offer that you find useful? I know I'll have to install iWorks and Photoshop separately; and one of the things that holds me back from purchasing a Mac is the various programs that are available for Windows only.
