First, you totally avoid what he said which is clear from your post. Then you proceed to make a blanket statement about people you do not even know. Fine, you do not like 8, cry up a river, but please do not claim you know what is best for everyone else.
Let me recap the conversation for you:
He: No one is forcing you to use 8, just use 7.
Me: I am using 7, but MS wants me to use 8.
He: No one is forcing you to use 8, just use 7.
Me: True, but if MS didn't want me to give them more money for a new OS they woudn't have made 8.
I am not avoiding what he said at all. What I am saying is that a company wouldn't develop a new product if it didn't want customers to use it. Windows 8 doesn't work for business users and business users are the bread and butter of Microsoft. How do I know that it doesn't work for business (other than countless blog posts etc about it)? The organization I work for decided to not transition roughly 10k of our desktops to 8 because there's no tangible benefit in doing so.
