That's awesome! I hope this becomes an available option in the near future.
Also, there was a story about a guy with a bionic arm in the news, recently: http://www.bbc.co.uk/news/world-europe-11607930
Sad to hear about that guy, and I hope it had nothing to do with his arm. If it played a role, it would be terrible for the entire field of research, knowing how crazy people are when one tiny thing goes wrong.
