I need to buy a new laptop, and I get the sense that some of you know a lot about computers. (Or, at least you know more than I do, which isn't hard.) I don't even know whether to get a Mac or PC, so I'm starting from square one.
It needs to be lightweight for carrying around when I'm traveling, and it needs to be able to work quickly with big, high-resolution pdfs and powerpoints for conference presentations. And a long battery life would be good for use during archival research. I have no idea what else would be relevant for making this choice. Help? Suggestions? Do you own a laptop you love that you'd recommend?
