It's one thing to present a different opinion and back it up with facts or other reasonable arguments. It is quite another to tell everybody that they should do what you think is right for them simply because it is what you have decided is right for you, then pass off legitimate counter-arguments as closed-mindedness.
Most of us here have seriously considered the merits and drawbacks of Windows 10. I had actually been looking forward to it until I learned about the forced update policy. When Microsoft wants to give me a free device, I will treat it as theirs, accept their choices as to what is installed on it, and use it accordingly. As long as I buy the device I use, I will consider that I own it, and I will decide what is or is not download or installed on it. Period.
Oh, and I still use Lotus 123 (97), because it is still the best spreadsheet software ever made. I also use Excel, for files I have to share with others, because I don't expect everybody else to conform to my choices just because I think they are better ones.
I sincerely hope your retail company has a more respectful attitude towards its customers than your comments demonstrate you have (or expect Microsoft to have) for people capable of making their own consumer decisions.
