I cannot comment, other than to say that they are a great customer. Infrastructure will continue to be a challenge and an opportunity. These problems were seen when cellular phone usage grew very rapidly, and we still don't have an ideal system. Basically, a chip carries the protocols for low-power radio communication, with a range of about 10 m. We can expect to see the technology appearing on Intel devices, digital cameras, etc. One fact of physics that may limit its expansion is that transmitting radio uses a lot more power than receiving it.
Idiots are everywhere.
If this issue goes away, we may see voice-enabling again. Again, there are major technical challenges. An airplane is a big faradaic cage, and when you put 400 wireless devices in it, you're bound to get some serious interference. Avionics rely on radio signals, which is why the airlines currently do not allow portable transmitting devices to be used on airplanes. My hypothesis is that systems evolve through their users.
