Thank you all for the advice. To answer CD we got another Dell, and that's about all I know about it. It's shiny, and it works. Having a bit of trouble still with the new windows. Don't like the layout for my pictures, and really hate the way my email looks now, but I'm figuring it out.
We also got two laptops for the kids. Lady was selling them on Kijiji (like a local Ebay sort of site) two for $60. They're not brand new, but after working on them for a few days Rod fixed the issues (both had viruses) and they work just fine. This way the kids can work on their homework, and download their music and stuff, without it ending up on my computer.
Still hate the tablet, but I do play games on it once in a while.
