@scratchme, I'm mostly a *nix guy on the programming front, so I was big on C for a long time. I actually started with C++, but since the more recent standards, I don't know if I'd recognize certain additions to the language today. I do like Python and Lua quite a bit, and in a particularly nerdy endeavor, I learned some 6502 assembly to program for C64 and NES. :P Never went anywhere with really any of this, but programming has absolutely influenced how I think, and I credit Eric S. Raymond and The Art of Unix Programming for introducing me to some more philosophical ideas in general (and not just in programming).
All that said, I have a Windows 10 laptop sitting in front of me, and I'm perfectly happy with it so far. I might look into some more C# and .Net stuff if I feel so compelled.
