Tizen holds the promise on shipping on lots of different devices. Samsung has already been shipping the Samsung NX-300M Camera for the last month or so but Today at the Tizen Developer Summit, Samsung has officially announced that this camera is actually running Tizen!
So, Tizen is now shipping... On a camera. On a related note, Samsung has let out some details of Tizen 3.0, planned for next year. It's going 64bit, will gain multiuser support, and will switch from X to Wayland.
