I had this idea about 6 years ago, when I first heard about Bluetooth. I love the idea that when someone calls, I can just glance at my watch and see if I want to take the call. Even better, I’d like 2-3 “quick response” messages, like “I’ll call you back in 5 minutes” or “Send me email instead” to send back to the caller that only take me one click to send.
The point is to make the cellphone call the same thing as if someone walked up to you while you were having a conversation. You have the option to make a quick hand signal or other indication that tells the other person if you are interruptable or not. I want to be able to do that discreetly when someone calls.
