A number of posters have indicated above that they found Linux more difficult to use than Windows. FWIW, my experience has been the opposite (I am comparing Linux Mint 17 to the older Windows XP, and have no experience yet installing / maintaining Windows 7 or 10).
My Linux Mint installations have always worked perfectly from the initial installation, which was easier than any equivalent Windows installation. (This is so, to the point that if I were to recommend an OS for a computer illiterate parent, requiring mostly browsing, office suite, and email capability, I would recommend Linux Mint hands down). I have always been able to run an emergency version of the Linux Mint OS from the install CD (contrary to the situation with Windows XP, where such emergency OS CDs never worked). A reinstall is trivial, compared to Windows XP. The basic OS capability is at least as good as Windows, and comes with an easy-to-use “Update Manager”, which has given me less trouble than the Windows equivalents over the years. I also get the Firefox browser, the office suite Libreoffice, the IDE Eclipse, etc., all of which like Linux are free, first-class, products, and all of which are easily updated along with the OS (except for the free Eclipse, which requires more screwing around sometimes). The only minor complexity in all this was that I initially had to download an ISO file and burn it to a CD, to get a bootable Mint install CD. Not a big deal.
Now I admit that the main advantage of Windows is the huge program base, including such as MS Visual Studio, Adobe Photoshop, Aces High, most other popular games, etc. However, this is a problem with the marketplace, and not the OS, and is a situation similar to that pertaining to my Amiga computers in late 1980. They too were technically superior, but eventually died out because of Microsoft / IBM's more successful marketing.
I am faithfully awaiting the completion of the MMO space game Star Citizen (2-3 more years??), and they have promised both a Linux and Mac follow-on version. Hopefully they will deliver on this.
