Re: Charm bar thing....
This was going to be my point, when everyone asked "is there going to be some kind of tutorial?" you forget to tell them "there is but we've neglected to let you see it"
I can't remember when the tutorial is shown but it's either part of the OOB experience or at first log in to a new user account.
If they don't get to see the video how do you expect them to know what to do?
How many of them would have know how to produce the start menu in Windows 95 the first time they saw it if they didn't get to see that weird animated arrow that flies in from the right first time you log in?
