My wife is a photographer that does a lot of heavy photoshop work (CS3 with Light Room), working with raw files from a Canon 5D. So naturally, these files are very large to begin with, and they get even larger as layers are created, etc. Also, she creates some pretty hefty coffee table books, and while in process, the file size can get really large (approaching a gig) not to mention large swapfile requirements, etc. ANYHOO - she's currently on a quad-processor PC with Vista and it's just terribly inefficient and slow. We want to move her to a Mac sometime this year. Given the above type of use (90% heavy photoshop work...10% internet/budget spreadsheets/etc...0% video editing), what would you recommend for her? She likes the idea of portability of a 17" Macbook Pro because she could take it with her to photoshop seminars, or move it into the "viewing room" when presenting to clients. But I wasn't sure if that's beefy enough and if she'd be better off with a Mac desktop for what she needs. Right now we can't do both, so it's either/or. Thanks in advance for the guidance.
