The power consumption angle is quite interesting - but I given the power saving they demonstrated wasn't really of an order of magnitude or more, then it might be hard to make it scale up to practical tasks and have errors worked out of it. Perhaps there are more savings to be made, but I would expect to see orders of magnitude less power for this stuff to be practical.
