What do you guys think about this?

Hey guys, I saw a new smart watch for tennis just launched on Indiegogo. It looks pretty cool.

Everything I've seen so far, like the Babolat, measures technique. This one keeps your score, saves your match history and game statistics, ranks you (not sure how), and helps you find players. Looks like you need one per player, so it'll need to become popular to be really useful.

What do you guys think? I just backed and am pretty excited http://bit.ly/pulseplay
