Let me just say that most of you, if not all, appear to be atypical users in that you are well versed in the very technical details of this all.
For us non-geek users, it is incredibly frustrating. Well, for me at least.
We don't know what this classic shell stuff is.
We don't know how to open apps on different screens now when previously it was a simple drag and drop.
We don't know that apps are now required to do things that were previously native to the OS.
Basically, all of this technical stuff that most of you guys take for granted is stuff that we don't know, nor care to know. It should just work out-of-the-box, and as far as I am concerned, it doesn't. That makes it a complete flop in my books...
