My tl;dr (too long, didn’t read) on Windows 8

Every one is a critic but I’d like to sum it up quickly:

Pros:
  • Built in pdf viewer
  • Built in ISO mounting
  • MUCH faster boot times and everything is generally snappier 
  • WAY BETTER multi-monitor support (taskbar on each screen is amazing)
  • WAY BETTER task manager (includes MS config to edit start up programs)
  • Much needed improvements in Windows explorer (Ribbon similiar to Office)
  • “Refresh your PC” setting that allows you to basically do a re-install without booting your W8 disk
Con:
  • Metro start screen (press Win+D to go to desktop)
