I would agree that you can BUY support if you have an enterprise version of GNU/Linux, but I bet less than 0.5% of the Linux users do.
But there is FREE support for any issue 24x7 on Windows Lenovo products which are under warranty. And this support is offered even at strange times such as 11pm on a Sunday night via telephone with no hold times. I know this because I had a problem with my W530 a few months ago and the guy was on the phone with me from Atlanta from about 11-12am and he only hung-up after I said thanks for the help! Such support like that for Linux would cost a user thousands. I think this is the main reason for the lack of desktop adoption of Linux. What else could it be? Ubuntu is literally easier to use than Windows 7, but I can’t even get one of my friends who uses Windows, to even try it on an older system. My friend who has a 64 bit Vista laptop, from about 2008/9 era had major problems with the OS recently; I begged him to try 64bit Ubuntu and get rid of Vista. He won’t do it. What can I say? You can’t make the horse drink. Ubuntu is like XP, but unfortunately it is 15 years too late. That’s why I say, forget the desktop, just enjoy Linux and quit trying to promote it. It promotes itself.
