What's the problem with a three-key reset? I for one would definitely not want it on a single key.

Re reasons to switch. Mine was when MS made the "Genuine Advantage" update compulsory. My installation was genuine and legal but I did not like being snooped on.

I regret to have to say that the lack of stability and, above all, usability was my main reason for switching too... from Linux back to Windows. I now use a Windows PC with FOSS everything except the OS itself.
