What to do with this i pad?

I've been thinking about what I can do in my class with this i pad. The first and most important thing that I am going to your this for is my main computer. I travel from four different classrooms at first school and use four different computers. This means I have to log into each computer and set up my lesson from drop box in every period. This i pad is going to make life so much easier. I already bought the cord to connect it to the smart board and everything! Other things that I would like to do is some exploring on google earth and perhaps some FaceTime or Skype with some people in other countries.
Until next time...&c.
