My ten year old son wants a laptop for Christmas. I do not have unlimited funds, so have been watching ebay. Are refurbished units necessarily a bad thing? What sort of things should I be looking for in a laptop for a kid this age? Should I worry about DVD capability? I don't want to be buying a new computer every year, but I know everything is outdated the minute it hits the shelves. We use satellite internet here is WV, and my router has been flaky lately--it's only a couple of months old, so I'm a little irritated with Airstation. Any advice?
