There are number of issues that wreak the whole experience:
1. Can't add dock to multiple monitors. This can be dealt with if I add Docky, but a sucky solution.
2. Can't right-click on any monitor except main monitor to add folders. Folders only appear on main monitor.
3. Can't capture an area of the screen on 2nd monitor.
4. CDs read in Chinese instead of English.
5. No clock settings in control center for normal 12 hour vs 24 hour.
6. Mini menu doesn't organize apps by type like Internet / Video etc. like large menu.
7. Screen tearing hell.
8. Nvidia closed source drivers don't install, have to do it manually.
9. No song preview and track advance for Spotify.
