Use Your Arm as a Smartphone?

Just when you think you have seen it all when it comes to technology, something like this comes along and blows your mind!

When you become the technology, there is often the question of safety that comes to my mind, first and foremost! After that, I kinda geek out and think about how unreal some of these inventions are! Your arm IS your smartphone?! Get out! (ugh ... that really made me sound old!)

I saw this video in the land of Facebook, you know, where all cool videos live and had to share it. The bracelet is even waterproof! As a mom, for me, there are a few ways to look at this. I hate missing important calls when I'm in the shower, especially from my kiddos or family. I also enter the bathroom expecting not to be bothered at the same time. A nearly impossible feat for moms, pretty much, since the beginning of time. Big or little kids still like to yell "MOM!" the minute you sit down. Next come the little hands under the door and your "Calgon" moment is gone.

Would you try something like this? (And the devil's advocate in me wants to know what the glitches are too!)
