Sony Clie SL10

So I ended up with an older pda for the mean time. (I only paid $20 for it.) It'll do until I save up more and decide what I really want. I am just curious of the capabilities... It says I can download stuff from palm os and movies and games, but it only has 8mb. I didn't think that was a lot? Also, is there a way to make it wireless? Can I buy a wifi or bluetooth thing for it? It says connect via modem, but no one uses modems anymore, at least not dial-up. And can I get gps for this? Any advice on this would be great. I know I can download the manuel on the website(the guy couldn't find his.) But I figured people that were more familar could answer in more detail. Thanks!
