Drew Blackard: When we do a new product, we always want to understand from our current users what they love about the device, different pain points they've had and try to resolve those. And when we think about the hinge specifically, these devices are really about portability and pocket-ability. So we want to make them slimmer and thinner in each generation. By going to what we call a zero-gap hinge, we're able to narrow the device down. That helps from a durability perspective because there's less space for any things in your pocket to get in between the device.
