Actually, my wife would love that device
She still prefers flip-phones in the first place, since they make sense to her as far as answering and hanging up (flip open/close), and a built-in resistance to drop damage.
She also has a terrible time with touchscreens, and would love something that she could dial using real buttons. She's used to doing that without even looking at the phone... something that's nearly impossible to do on an all-touch phone.
That's the thing, it's still a primarily a touchscreen phone, but it's got that pointless keypad on it. You don't even get the benefit of size that you'd get out of a regular flip phone. Plus, with the two screens, it's likely not any less fragile than a regular smartphone.
You gotta admit, the thing is kind of a dumb idea.
