I can't remember all of them , think there is a better networking situation in the event you have more than 1 puter at home. But mainly, the OS is so important, I try to have the best at all times (see I told you I was only a level 7 geek).
The only relevant difference I found is that you can host your own website (with email and FTP) in your computer, but for doing that you have to have the "right" Internet connection, (Static IP) and an inclination to do so... (it's not always a good idea)
And you can always add free 3rd party programs to get the same functionality.
