I could use a small laptop for field work sometimes. That is, mostly it just has to be good enough power-wise to be able to load and view huge image files (I know it'll be slow), as well as run XP. I don't care about game playing or wireless. I do care about battery length, if any are a lot better than others. I'm guessing I'd be looking at 1-2ghz, more or less, on used ones?
I figure I could find something cheap on ebay or similar, but I know nothing about laptops; what brands are more reliable (important if you're buying used I guess?) and what would be overpaying? Or am I better off just buying a cheap new one for $800-$1000?
Example: This Toshiba 1.8/512 on ebay is bidding at $400 at the moment. Would it do what I want ok? Is that a decent price for what it is?
