Very interesting and kinda funny, that you ended up at Debian :) But I can understand that.

One thing that tells me is, that it is good to have multiple operating systems, open ones and proprietary ones. They can all learn from each other. And I long for the day where Windows will offer me an equal commandline experience like Linux and where Linux will give me a decent desktop environment, where "it just works". In some ways we're really close to that day. In many ways not so much.

The only thing which sometimes gets me is, when I think about all the time me and mankind in general did (and will) waste on learning the intricacies of operating systems. It's funny and sad at the same time :)
