All this is cool but I hate my smartphones. I find them very intrusive because anyone can call be anytime and interrupt whatever I am doing
Logical fallacy. You have the power to turn this device off and mute it at will. If you choose not to do that, you have no one to blame but yourself when your enjoyment of the sacred present moment is rudely interrupted by a noisy gadget.
When I go to the beach, I don't even bring my cellphone. That way I can go in the water without having to worry about if my phone will get stolen.
