Millennial anti-theft device

[Toolmaker51]

I'm wondering if we will soon start seeing anatomical changes in the orientation of hand bones to accommodate cell 'phone use?

Oh gracious me, we'll probably evolve with that as a root cause. Because their grasp of ergonomics is not apparent.
I stopped liking cell phones when pull-out antennas disappeared. Sized like cordless phones are now, decent keypad, hand filling yet operable in the palm by thumb, batteries with sufficient mass to generate a real vibration, screen not dominating the device.
Biggest joke is keypad or touch screen crowded in the lower margin.
I always thought the screens should be lowered, so thumb can flex over first and second fingers; like almost EVERY tool you can think of.
