It's no surprise that HTC appears to be taking a cue from the iPhone 5's design pattern in creating a sleek aluminum-bodied phone.

Whereas Apple went with a flat backside to keep the iPhone's overall thickness down, HTC wanted a more ergonomic curved back.

HTC has said over and over that they wanted to create a seamless product, and the absence of any exterior screws is a testament to that.

Unlike the iPhone's volume buttons, which protrude from the case, the One's buttons lie flush with the sides so as not to interrupt the body lines.
