I do not understand why a rebranded geocities website to give everyone their own personal webpage, a 140 maximum character length bulletin board website, and glorified touchscreen bookmarks for websites are still considered to be examples of innovation. Facebook, twitter and apps have been around in some form since the beginning of the internet.
Lab-on-a-chip technology has the potential to be the science fiction equivalent of a medical tricorder. Every doctor could have one and give instant patient feedback. Yet the expectation for this start up is to get it perfect from the beginning. They may lose all their VC's money but I bet that DARPA would still bankroll them.
