I hadn't thought of that, but no, I haven't

@FearlessFly The reason I ask is that the Ipad, I have paid for every app I used. Windows used to be the same, I need to use Autocad. Linux has everything free, a lot easier to use once the learning curve is tackled, It is a lot easier than when I started using it back in 1995, I think. Now, it just works and using apt-get or just apt upgrades all the programs, installs anything you want to use. There are many other tools that make it easier to use and fix. It also does not have to be rebooted when it fails. I once saw how long it would go and I got something like 460 days until I did a total rebuild and upgrade. This is impossible with Windows.
Reminds me of when Microsoft wanted to charge the School district of Portland Oregon for every machine license used. A call went out and there were going to be enough people to put Linux on every machine in the District in one weekend. Microsoft let it go so there would be more kids used to using Windows than Linux.
