I guess it did, and your response didn't clarify things. Suppose I listed the choices as
"Apple, Debian, Red Hat, Suse, Ubuntu, Windows"? Putting them in nice alphabetical order, and leaving out the choices that require a bit of tech knowledge. (I'm not sure about SUSE, but I suspect it's just as easy to use or install.)
The real limit is that most people don't install an OS, so they just use whatever their computer came with. The last time I installed windows it was harder to install than Debian...of course that was back in the 1990's. I haven't touched their updated TOS, and even in the 1990's I had someone else click through the requirements. (OTOH, Windows 95 and 98 were relatively easy to install...but then you needed to get all the drivers installed. So Debian was still easier...but that's not fair, because the Debian I'm comparing against is at least the 1998 version, and often one slightly later.)
