where I am ( www.outpostcentral.com ) we look for extremely low power, so we have micros dedicated to that. Most sleep currents of processors like this are just too high for frequent battery operation. However we do use a higher power ARM processor for comms / high level processing functions, but that gets completely turned off for the majority of the time.

So this is still really cool, conceptually, this brings a very good platform to probably the lowest level that's practical. I've put it on the list of things to consider for one of our new product designs.
