You do realize desktop Linux distros have been unbelievably easy to install (or even run from a Live CD) for the last decade or so don't you? Nobody has been "forced" into using Windows just because it happened to ship as the default for a very long time.
That's like telling someone that "a space shuttle is really easy to use, someone on the ground actually presses the "launch" button for you!"
Sure, automated initial installs have been all wrapped up in little wizard-like packages. That's not the point, it's the ongoing installation and management of packages and versions and such that you have to keep up on.
I get Linux, I do. I have used it on spare PC's before. But I just don't have time to use it on my main machines, because while I'd love that much time to tinker around and do all kinds of clever things with it to hone it to be the ultimate OS for me - I just don't have that kind of time to spend on it consistently. You have to "keep up" with Linux as a hobby way too much for folks that just need to get tasks done on a PC when they sit at it (especially with tablets in the picture, as for a lot of us we spend a lot less time tied to larger machines since we do a lot of consumption that way now).
It's one of those things that I'm glad it's there, I wish I had time - and maybe someday, but since I don't install crap on my PC and I don't go to sketchy websites (well aside from this one LOL), and I take a modicum of security precautions, I do OK with Windows. I never have to ask if I can run something on my machine, why I buy a product that can connect to a PC via USB or network (camera, Blu-ray, etc.) I never have to wonder if the driver software will work for me or if I'll have to spend hours hoping to get it working with whatever I can scrounge up, I never have to search out solutions around how to do what I want, etc.
In the end, yeah, Windows, yuck, but deal-able, and it's really disingenuous to pretend that because they have dumb downed the initial install package to Windows levels, that the actual ongoing user experience of Linux is nearly that plug and play for most folks, so to speak.
