I came to this thread late. That said, I love the commercial.
It's funny because it's true. I was out at the pool a while ago with my nook and my cellphone. It was around 2:00 in the hot florida sun. I got a phone call, couldn't see who it was that was calling me, nor could I find the touch sensors to unlock the phone to answer. The sun turned my phone into a black screen of nothing. I could still read on my nook though...I just couldn't switch books because I couldn't see the screen
Also had the same problem while trying to play a game on my iPad while waiting for my oil change. Damn sun.
