Well, I've discovered that I'd still prefer a smaller device, at least if I'm going to use it as a telephone. While it is downright beautiful, it's also downright ungainly; holding this huge plate of glass up against my head is just never going to be as comfortable as would a smaller device.

(And, btw, it turns out that having sweaty hands is actually the key to getting a grip on an HTC One. If your hands are clean and dry, the phone will slip out of your grasp as quickly as if it were a bar of soap...)
