But....
...my Bluetooth is off 90% of the time. I only turn it on to listen to music or in the car.
Add to the fact I'm on a buggy version of Android that cripples internet connection over WiFi, I have no intention of turning it on by default.
Then there is the big fact, I don't carry my phone with me all the time.
And what about my parents who don't have a clue what Bluetooth is.
