It's an odd decision to force onto people, but when most people actually use it, it's a pretty good interface and you realize the Start menu was actually less efficient in many regards.
Then all of a sudden, in one single new version of Windows, it's all gone. Now 90% of people who have used this brand are completely lost. I gave it a fair shot and had to Google everything I did. I had trouble even getting to an internet browser.
Maybe an interface without a start menu is superior, but at the very least Windows 8 should have been a hybrid version which came with the Start button and taskbar enabled by default and a "new" way to remove the start button and taskbar.
Having to move my mouse in a certain corner of the screen to access a backend "metro" area (which is the only way to actually get to program or files now) is NOT good UI design.
Can you please explain how can you consider it superior to make everything you work with disappear, no matter how big the screen you work with is, just to start another program? I'm not interested for the screen sizes of the phones, but 21 inches and above. Then do the same discussion for all non-touch monitors and touch dependencies.
Metro existed before Windows 8 on the Windows phones. There's no good UI reason to make all big screen desktops behave like small screen phones. It was a pure political decision and they deserve every bad voice there is.
Oops, can't do that! The PDF viewer is fullscreen-only.
Edit: OK, so apparently you can[1] snap the default pdf viewer, but I can see it's not going to be a very nice experience having either a video or the pdf viewer occupying 1/3rd of the screen.
