Want to Watch a Movie? Don't Upgrade Your iPad Before You Get On a Flight 

Here's just a little tip for you. If you plan to watch an awesome historical movie rented from iTunes on your flight home, don't upgrade your iPad to the latest version (for me, 6.0.1) before you get on the flight.

Or, if you do, at least connect to the internet and make sure iTunes reauthorizes your iPad to watch the movie.

Otherwise, you'll get on the plane, hunker down to watch it, and instead, get a nice error message of "Cannot Open" over and over again until you give up and realize it ain't going to happen.

Thankfully, I've got another leg of my trip and I found wifi in between. Open up the Videos app, and all of a sudden the iPad remembers it's allowed to play the movie.

Now I need to go learn about the history of our 16th President and how he ended the vampire plague.
