appollo :
wow just a few trolls lurking in here lol
I just rolled out 3 student labs with win 8.1 and we tested with the students before (windows 7 and after windows 8), the only thing that we did was configure the start tiles so that they had just the tiles that they needed to use, it was faster to load and also faster for the student to find and open the application that they wanted.
Sure it looks different and if you dont spend any time to adjust it to your needs or bother to learn it it will be horrible but once you understand it and set it up its much better
Completely unscientific. You compared it to what? Selecting the app from the start menu? An icon on the desktop? The taskbar? Of course pressing the first and only thing they see would be easier and faster.
How about you test opening an application starting from the desktop that is not tiled on the start menu, or at least flood the start menu with about 50 other applications. Or better yet, test copying text from a web page to a word document with both web browser and Word running in metro mode.
