I use mine as a VPN gateway, web cache, media streamer, and source code repository. Sometimes I even use it as a pleasantly-silent desktop, since it's on the same stand that holds my monitor and keyboard/mouse. Because it's right here in the house, latency and bandwidth are great. Because it consumes so little power (even with an external 2.5" disk drive attached) I don't worry about leaving it on all the time. It's just a good do-everything workhorse, that also happens to be small enough that I could toss it in a bag and take it on the road with me if I felt like it.
