Here is an archive of what my desktop running Linux has looked like since 1995. There is about one screenshot a year. I blogged about this collection a while ago.
All of the hardware works and I now have a system whose OS will still be supported in 2019. It's running four OpenVZ virtual machines as well as a Gnome desktop quite nicely. As can be seen in this screenshot, the old school media player XMMS still runs nicely, as does Firefox and Xterm.
Compared to older screenshots, the fonts look a lot nicer. Not only does Linux come with a nice set of open-source fonts, but also Microsoft's core fonts have been legally installed.
