Today, Paul Pierce is a distinguished designer at Motorola. But 15 years ago, he was on the original design team of the Razr—the impossibly thin phone that would go on to change everything—and he wasn’t so sure about how it was shaping up. Specifically, he wasn’t sure about that big chin.

Another detail the design team obsessed over? How the phone sounded when it closed. They were particular about the materials used on the bump stops that padded the screen from the keyboard: Technically, a material like felt could have made this gesture silent—but what fun would it be to hang up on someone without an audible snap?

I absolutely loved my Razr. It still might be the phone that is the most tactile and the most fun to absentmindedly play with and spin in your hands like a fidget spinner.
