I also use Siri all the time, and my usage is only increasing as I learn the spoken instruction set, and Apple improves the same.

I've even found myself thinking 'Siri, where's my phone?' when I can't locate it in my flat. Siri is addictive if you learn to use the tool.

The Moto X (and it's three Verizon siblings) can actually do this, with their always listening feature.

Yeah... not so keen on having Google listening in on me all the time. I prefer to pay for my gadgets so I'm the customer.
