And what happens when (not if) the phone crashes? No thanks. One of the charms of our bikes is their "old school simplicity". That may sound hypocritical as I have my iPhone mounted on my handle bars with a USB power plug and connected to my helmet via bluetooth. But, that is so I can earn my living while riding (GPS navigation, phone calls, etc). I have the option of not connecting my phone, when I just want to enjoy the ride. I have enough tech in my life already, I don't need to add to the complexity with further smart phone integration into my bike.
