Linux is great in the back office and on servers. One the desktop it's fragmented and hobbyist friendly without meeting average users needs.
Let the condescension and flaming begin!
Okay I am not going to flame you. A desktop operating system is pretty much just an app launcher. If you had Linux versions of MS Office, Adobe Photoshop and Elder Scrolls V: Skyrim than more people would be on Linux.
If you want to covert people to Linux you have to convert them first to using Libre Office or GIMP on their Windows PC or Mac. Once people are comfortable with cross platform software Linux use will increase. As more users come in, maybe more developers will follows.
