If walkie-talkies were invented today, and someone proposed they be called "walkie-talkies", they'd be laughed out of town. It's like a baby's name for something! How does that leverage any synergy?
Instead, we'd end up with some terrible acronym like PZIMCD (Personal Zero-Infrastructure Mobile Communications Device), or some almost-meaningless, "how does it make you feel" marketing "funky" name like Yuni (it's a commYUNIcation device, get it?). Ick.
