My question is simple. What (if anything) does Ubuntu Server Edition have to offer to home users?
This question is mostly out of curiosity really, but I like asking. I've got a home network set up here with some 6 to 7 machines (most Windows, one Linux). And I was wondering how useful would it be to have a dedicated computer in my house running Ubuntu Server full time. We've had an awful experience with file sharing so far, would it simplify file sharing/transferring? Would I be able to limit the internet bandwidth granted to each PC? Would I be able to monitor in/out internet traffic (both real time and monthly statistics)?
Last, and most important, if I'm completely off as to what Ubuntu Server actually is, please say so. I am completely new to it.
