For a variety of reasons, I'd really like to pick one of these up. Actually two. Optical audio out, music streaming, wireless internet, etc. I also hope to have a mac somewhere down the road. I know these are Mac + PC compatible, but what I haven't seen answered is whether or not it can be installed from a PC, without ever going through a Mac at all. Is it PC-compatible in a PC-only scenario? I know it can be used to extend the range of a wireless network, but the wireless in my house is an ancient Linksys turd; I'd like to use the airports as THE wireless network. (and in a pc-only environment until I get my Mac)
