Two problems I saw:

1) The voice recognition seems to be overly contrived, even moreso than usual technology demonstrations. I'm sure anybody who views the takeaway example with a critical mind can see how that would be incredibly hard to do for real.


2) Following on from that, are they promising a product that can do that out-of-the-box or is it an example of what a developer could do with the hardware? Will they will claim the "hard stuff" like the takeaway scene isn't actually their responsibility and a takeaway app developer needs to do all of that, they will just let them listen for certain keywords or something.
