How often do you find yourself needing to dial a number when you have no service? I can't see voice dialing helping much in this situation :-)

Of course, you can get the normal voice control back by turning off Siri in your iPhone's settings, but I admit that toggling this when you're in and out of service should probably be automatic.

I'm sorry for my Computer Engineering bias showing so obviously here, but..."basic elements"? If you, as a Computer Scientist, see devices such as microprocessors as "basic elements," I think you need to branch out a bit. Sure, there's much more to a computer system than the processor, and you need plenty of software to get all the hardware components working together, but I still would classify an ARM or Intel or GPU (or countless other types of) processor as a "complex system."

Nothing against Computer Scientists or software engineering or anything...lets just give credit everywhere its due.

There, I feel better now :-)

I didn't have any problem getting my Roomba remote control app approved this past week. Check it out: http://www.brianhpratt.net/roomote/

It's available for free on the app store. Just search for "roomba" or "roomote"
