I once had 16 customers running ubuntu linux. I am a full time professional computer consultant with a few hundred regular residential customers. When Vista came out, I thought this was going to be the end of microsoft, so I started looking for alternatives and landed on Ubuntu. I setup a computer at home to learn it myself, and started installing it for customers that only needed a web browser. I spent WAY more time than was acceptable on issues like flash-based games and printer support and streaming TV that all should have "just worked" but didn't. I can't imagine supporting people that expect to do things like scanning and mail-merge and burning cd/dvd and editing videos and/or pictures and syncing with their iPhones like a lot of my other customers do effortlessly with their windows computers. I played with a few different popular flavors but never found one better than Ubuntu (at that time), so I finally decided Linux was not worth all the extra unbillable hours I was working, and switched all 16 customers back to windows. Every time a new distro makes it's way to the top of the list, my eyes get big, and sometimes i'll install it in a VM, but the "just works" factor just isn't there yet.
I still use headless linux servers in production for about 10 of my business customers for things like email servers, web servers, dns servers, but i'm starting to use it less there too because hMailServer smokes postfix and IIS smokes Apache in the "just works" factor, which became a lot more important to me after I had a kid and my time became more valuable to me. Webmin helps A LOT with the "just works" factor, and if it wasn't for webmin, I probably would have already switched most these linux servers back to windows servers. I love spending dozens of hours troubleshooting linux issues just as much as the next linux geek, but it's different when it's for a customer and I can't bill all those hours.
Hope it works out better than the digital television transition in the United States in 2009. I went from having 6 usable channels to about 20 unusable channels and 1 usable channel. I bought a huge 30' tall 10' wide outdoor antenna, a good amp, and tried 3 different brand receivers before giving up and getting rid of all my TVs and switching to torrented content. I would be in the middle of a show and it would start cutting out as the clouds moved by. It always cut out at the most frustrating times. I also hated the huge delay required to switch channels. I would be so pissed if they made FM useless. I guess i'd have to get an MP3 player for my car and spend a lot of time keeping it updated with the latest music.
