Does this set-up exist?

Hello, I've been looking around for several hours trying to find a laptop that suits my needs, and I'm convinced there isn't one out there to do so. My requests don't seem too demanding to me, but here they are. I need something on the smaller side (netbook, thin & slim, mid-size). It has to fit into my flight training bag. I would say the maximum dimensions would be 12"W x 10"H x 2.5"T. It would be nice to have wifi, but I could settle for ethernet connection. It doesn't have to be extremely fast or have a lot of memory or storage, just enough to surf the web at a hotel and maybe throw some music on there and save some documents, etc. Here's the kicker though, all of my training material at school is on DVDs. I can't find anything that small with a DVD optical drive. Also I would like to stay under $500 if at all possible. If you have anything in mind, or any solution to the DVD issue let me know, I'm easier to contact at jones14@siu.edu

Thanks,

Nick
