I love that Nike is getting more and more progressive in monitoring people's stats.  While I myself will probably have no need personally for this product.. I'm slow, have no up's, which means I'm not dunking on the court hahahaha..but it's still forward thinking for serious athletes who are working on their game all the time. The only way one can improve is if there are measurabilities to gauge your progress.  Your best competition is yourself.  Looking forward to what they come up with next.
