Oculus Rift's Tuscany demo was built with a good ol' fashioned keyboard and mouse setup in mind, but now it's unofficially scored support for motion controls.
With USB support in the SmartDock, they can also use a wireless keyboard and mouse to write emails, browse and post on Facebook or watch videos from YouTube on their TV.
The mouse options in particular seemed like the shining stars of the batch, with hand comfort and support that seemed perfect for getting through a game of League of Legends or Dota 2.
