To those arguing Siri vs Google: Don't be so narrow minded. They both have strengths and weaknesses. I use both on my iPhone, choosing whichever is best at the task at hand. I use Siri to send messages, add appointments, launch apps, etc. I use Google to search for addresses, phone numbers, restaurants, and the web. I wish Siri did the streaming thing, but now I know it will in a couple months.
Apple and Google keep fighting each other for the best voice recognition, and that's hugely beneficial to us consumers. Let them fight over us!
Most importantly, as Louis CK would say, WE ARE TALKING TO OUR PHONES AND IT UNDERSTANDS US! WE SHOULD BE RUNNING AROUND GOING OH MY GOD!!
Enjoy today's tech. It's amazing!
