I have run it in the past, can do various simple things, nothing fancy. Now I have no use or need for linux over windows, but I want to really learn it inside and out, problem being I wont do that unless I can really find a good valid reason to do it for my own good. Now that being said, give me some hard core reasons to use it over windows for any of my uses. I want to setup a file server for my music, not for media sharing just for holding it mainly, but that can be done under windows just fine. I am also considering setting a system up for media serving, mainly a HD TV card to output to numerous TV's *not going to use a video card, a professional setup much more like hotels and your cable company use for things like on-demand *comcast*. I have heard Myth TV is one of the best for this, but still not sure if that's enough to push me over from Server '03. I also do lots of music and move encoding/transcoding. Have been considering setting up a mail server with dyndns. That all being said, anyone have any solid reason why to use linux vs Server '03? Besides cost as it doesn't matter I already have Server '03.
