My last question... So in my eagerness to buy myself a MacBook, I think I'm buying one for my parents too (the base version). My mother is concerned of using a MacBook at home and a PC at work; I've told her that everything is interconnected, from flash drives to files. Obviously the Office suite (including MS Publisher) is compatible, but I have run into trouble when creating PowerPoint slides on a Mac and running them on a PC -- I get uncompressed TIFF file errors or something. Are there any other things I should tell her about? I figure if she's going to have to learn a new OS, it might as well be OS X rather than Vista, but what are any potential pitfalls for someone who is pretty un-tech savvy.
