To connect to the television. Wireless keyboard and touch pad. I actually got it a few months back, but I haven't had the time to play around with it. Now I am goofing off with youtube videos on the big screen, netflix, entropysink, random news and content, bill paying, etc etc... all from my TV. Swipe side to side for desktops.
Not previously being a MAC guy... I am getting the benefit of playing around on a Mac as well as having all my entertainment from the couch. Freakin' love it.
