Some of these new metro apps are pretty cool. However, on my 27 inch monitor, the full screen really annoys me. What I wish, is that I could size them, and put them where I want! You could put them in a box, I could drag them around the screen. I dont know, you could call them 'windows' or something.
For my use case, windows 8 is a complete waste of time. The metro interface just gets in the way. In standard form the new start screen is slower and takes more time to use.
2 Common use cases for me:
Windows: Aim to the Start Button Click, slight move to programs, click on program.
Windows 8: Move down to the left corner wait for the start to appear and click. Now move the mouse to the app I want which could be the whole way across my 27 inch screen, and click on program. Or worst case, move to the far right of the screen to scroll the screen across, and then move up to the program to click on it. On my monitor, that can be alot of mouse movement just to run one program.
Windows: Hit start, type calc. Hit enter. Very quick. (unless something cpu heavy is running - may take a while to appear)
Windows 8: Hits start, type calc. hit enter. This is noticeably slower. The search list takes much more time to populate.
Windows 8 without a start screen replacement for me is terrible. Windows 8 with a start screen replacement offers nothing more than windows 7. It feels a little snappier but that's it. Running windows 8 for while now, and I just don't use metro mode at all. As I opened with, If I could window some of the apps, Id possibly use them, but without that, there's no point.
