I'm going to be getting a laptop from new, My budget is £800. My Requirements- Will be running multiple instances of excel, using wireless a lot, good battery life, good portability. Needs to handle lots of apps at once. As for GFX nothing fancy as the most it'll do is run a dvd every now and then. Processing power ideally suited towards running large number crunching in excel which currently takes an hour to complete (automatically (vba)) in Excel on a P4 3.06ghz pc + gig ram. Suggestions?
