You turned snotty pretty fast, and without having read all of the thread.
I work in a field that requires me to show objectivity and critical judgment. I deal with Windows 10 with the same approach. As for your claims:
(1) You claim that because Win10 is free "temporarily," no one should pass up the savings. But you do not know what the ultimate cost will be, or what form(s) it will take. Accordingly, you have no way to know whether there will be net savings. Those
who say that there is no such thing as a free lunch and are not willing to be lured into a loss-leader trap are wary for good reason. Your obliviousness to this risk, on the other hand, is a disservice to your clients.
(2) You say Win10 is more secure than previous versions. So far, no review that I have read demonstrates this, and a couple of reviews discounted it. Your opinion is unsubstantiated.
(3) You say that the Win10 update process is "better" that previous versions, with fewer interruptions. Since you do not explain why this is so, I must infer that it is because the update process is automatic and involuntary. In other words, no one is
bothering the user to ask his permission to make changes to his machine. And that, clearly, is "better" only in the sense that you prefer it that way. Others quite reasonably disagree, and prefer to have some way to control what happens. You also overlook
the widely reported fiascoes wherein recent updates have screwed up people's computers.
(4) I can't make out what you're babbling about here.
(5) "The app store is great," you say. Now if I need a Microsoft app store, I'll find it. I do not need or want the OS to interrupt my work to lead me to the app store.
The overarching point you missed in your hop-and-a-skip through this thread is the importance of respecting the customer's right to enjoy quiet possession and use of software previously licensed from M$. It is only when the customers have free choice--when
their rights are respected, and they are not tricked--that the Win10 adoption rate means anything. What do you contend, that the customers ought to be forced to go along, for their own good? If Win10 is as advantageous as you claim, why do they need to be
forced?
Perhaps you ought to show more respect for your father, by the way. He was right about Lotus 1-2-3. It was a better product than Excel until IBM dropped the ball with version 9 and opted to concentrate on Lotus Notes. Microsoft used that chance to finally
catch up, and with no further investment being put into 1-2-3, Excel then overtook it.
