I guess an apartment would rule out running cat5 (unless you wanted to do it along the walls, but that wouldn't look too good...but on the other hand, you don't need your security deposit, do you?). Nothing's wrong with USB for wireless, but wireless is expensive right now because it's so new, in addition to the fact that it's not secure at all. It's like a cordless telephone: all your information is broadcast in all directions for anyone with the right equipment to listen into. If you have phone jacks in the rooms you want to network, I'd say go for that. It's much cheaper, and they have both USB interfaces and cards you can install, the USB obviously being the cheaper. Right now, wireless just has the "Oh cool!" factor to it aside from limited use in corporate offices and similar situations. If there AREN'T phone jacks, you might want to investigate a new networking technology I read about that uses power outlets. I think Intel or 3com developed the technology, but I don't know how close it is to be released or even if it already has been. In your situation, I would only recommend wireless if none of the other alternatives are feasible. I was thinking about wireless for my house just so I could move my laptop around and even go outside, but that's just for convienience, nothing more. I could get along just fine with the phoneline networking because we have jacks in almost every room.
