Don't buy Dell. Crappy computers. I bought one, problems from Day One, I call it "Dell Hell". My Asus laptop seized up on me and I lost some of my son's movies (he had made them, he wasn't happy). Don't bother with a Microsoft Surface either, overhyped and low on performance.
I've had my best luck with HP and Lenovo. I also have an Acer Aspire laptop from 2009, and aside from its being antiquated, it's been a solid performer, heavy as an anvil, but a good little machine. I'm going to repurpose it as a DVD player for my son to use on long car trips.
