I am here in Anchorage, Alaska, and was curious as to whether I could use the Back to my Mac feature of my OS X operating system. So, I opened my laptop and attempted to create a Screensharing with it = and lo' and behold, I was able to actually SEE the screen on my home Mac. I was even able to close some windows and quit some programs.

Then I tried the usual connection so I could move a document between the machines and, even more to my amazement, I was able to do that. With no additional software, only using the OSX on my Macbook Air.
