Not sure in the video, but on their website they have a picture of the desktop with a streetdeck icon, and a picture of the frontend and that is streetdeck also. SNO
but streetdeck isnt it outdated? i havent seen anything new for it in years, you can try out centrafuse or Ride runner . i've been using centrafuse with my setup and it's pretty quick which is what i love about it. boot time is just under 15 seconds.
