Ditto. I find it bizarre that there's people who use the same device to span pictures of their weekends and their kids, as photos of whiteboards with highly-confidential trade secrets. Tawdry jokes with friends and family alongside messages from your manager.
To build on your analogy, in some cultures people use exclusively one of their hands to eat, and the other to clean their butts. We could learn do the same with two phones, I guess.
