Hal - Deploying Windows 8 tomorrow? No
As I have said before, I am piloting Windows 8 in my IT Department first.
Heck, most of our machines are more than three years old and running on XP. We will have all of them upgraded to Windows 7 in less than six months. The work is underway.
I worked as a research immunologist for over 15 years. We had an expression in the lab. "Always the control, never the experiment."
I do not experiment on my users by giving them new software until I have used it and feel comfortable with it. My users are the control. My IT staff are the experiment.
In addition, waiting a year or so has some added benefits:
1. Any major flaws and vulnerabilities have probably been worked out.
2. SP 1 is probably already released
3. Many users are probably already familiar with it from home use.
