Bring back the start menu and allow a configurable ribbon and Win8 would be a worthy upgrade.

That swipe left (even on my touch screen laptop) is an abortion of the highest order when other windows are in the way, and being that I use two monitors in extended mode I can't just whack the mouse into the left corner to bring up the start screen, I'm forced to radically slow down my mouse move and bring it to a perfect stop before flicking into the next monitor, doable but aggravating and annoying.

And I'd love to meet the designer who thought putting the shutdown / reboot options worked well in the settings screen, not exactly intuitive - maybe on a tablet since it's rarely turned off, but a desktop / laptop? Just dumb...
