I think this technology is awesome and has a lot of potential, but I don't know if it is easily defensible against the giants like motorola and verifone. How easily can these companies come up with software and a headphone jack that does the same thing? Most importantly they got a huge distribution channel with all those nokia phone and point of payment device users currently using their existing product. So if these companies do come out with a product that copies square they can quickly roll it out faster to a market they already have an establish presence in. This device has huge potential in emerging markets FYI. Also, in the end I think one of larger companies will buy Square out after a couple of years.
