According to Samsung, the curved glass is created by a process called 3D thermoforming, a process of heating and molding the glass. While it looks slick, it comes at a cost—in this case eight times the cost. That's right, what was once a $3 part could now cost Samsung as much as $26 due to low yields.

A recent report claims that Samsung's curved-glass supplier is only getting 50% yield, and that's pretty awful for the environment. Manufacturing is already rough enough on the planet, and this means they've got to make two screens for every phone.
