let me throw that question back at you.
Do you always think that change is not good, no matter how good it is?
See how I loaded the question? Same as you. You loaded yours with "no matter how bad it is".
You are entitled to your opinion of course and they are welcomed, but everyone has their own and their own experiences. I remember how, in the office where I worked, Civil Service Social Security Department here in the UK where I was in charge of the change over from Windows 3.1 to Windows 95 for 150 users, there were groans and dismay at the impending change, not just from the users, but from management as well.
I took to the change easily, it was my job to, and after a while so did all the users.
But then we moved to Windows XP....
I don't like change. I don't like many things about the modern world that has changed so dramatically since I was a 20 year old or so. But that's not the issue here.
The issue is a new OS that you seem bent on telling the world that it is going to fail. it might do, but also it might not. Only history will tell if you are right or wrong.
Have you tried it yet?
