Most of the changes in Windows 8 result in less mouse movement, clicks, and less steps needed to do tasks. This is a good thing, please provide some evidence contrary to this rather than something anecdotal.
As I've already stated in another post, just trying to close a program seems non-intuitive & harder!
Obviously it depends on the program (some still have the "old-fashioned" arrangement of a an "X" in the top right hand corner) but to grab/drag/hold (until the shrunken program reverses) seems harder than a simple click!!
The Apps page doesn't allow me (or to be more precise, I haven't found a way of doing it) to edit it so only the relevant Apps display - this means I'm invariably having to scroll to look for my App (***).
The fact that some programs "obliterate" the Task-Bar means that I'm no longer able to simply click between Programs, but I have to do the Alt-Tab approach!
The other thing that is non-intuitive but, until I managed to kill it dead, when I tried to save a document to "My Documents" (as I had set in the default) it tried to save it to a "Documents" directory on the Skydrive - "losing" my document!
Thanks to AEP for pointing out that there is a "hidden" facility for searching for the App - I say hidden because, yet again, it is NOT intuitive that I would start typing into "thin-air" (as there is NOT a Search-Box present) & a Search-Box will magically appear!
