Fascinating insight into one of the biggest email operations. I'd be very interested to hear how the other companies in this space differ or are similar. Question: Is there a curve where pushing this processing back to the phone will become possible? The most powerful counterpoint at the moment is battery life, but I do see that improving to a plausible point where this sort of continual processing is feasible?
