I have Win 8 with Classic Shell. I have uninstalled all the apps except Skydrive and Store, 'cause they can't be removed, I just un-pinned them from the start screen.
Once you have got rid of that stuff the metro screen is usable, but I still work the old way with desk-top icons and the start menu, depending on the type of program. The tiles for programs are just huge, not stupidly huge like the tiles for apps just a bit daft large. If they could be reduced in size it would be a big improvement, then with the grouping functions the start screen would start to become actually useful.
I decided to skip Win 7 all together and go with Win 8 as I considered it more future proof.
The biggest problem with windows 8 in my book is no Solitaire, Mahjongg Titans or Minesweeper
