This last comment is very insightful and addresses something I've thought about from time to time.
You pay whatever it is that Windows costs (no, it isn't free just because it's bundled on a computer), and then what do you have? Actually, not much. You have an operating system and a few tools (and maybe a bunch of bundled demo crapware).
You install Ubuntu or Mint or similar, and you have a suite of tools, and the means to easily install more, for free. Like Inkscape, as the lead article discusses. Within half an hour or less you can have full-featured computing that should meet at least 90% of the needs of 90% of users (maybe even better than that). I'm not going to get into the arguments about specialized tools or high-end features or cutting-edge gaming; if you truly need such things, go buy them and put them on your Windows system.
Linux has served me for many years. In the early years, things were rougher around the edges, but today, it's night and day difference. As I'm not much of a gamer, there is little or nothing that I need Windows for. I "get by" just fine with GIMP, and the new Inkscape is amazing, as is LibreOffice ... not to mention EMACS, of course :)
Sorry but I just don't see a personal need to spend money on software.
