Amir Efrati, The Wall Street Journal:
Motorola also ran into difficulties when it looked into using a bendable screen and materials such as ceramics that would allow the company to make the X Phone more stress resistant, use more colors and mold into different shapes, these people said.
We do want more rugged phones out of the box, and without having to protect them with ugly cases. But a bendable screen? I think that’s the wrong approach. A bendable screen is easier said than done. Assuming a candybar design where the display is integrated into the chassis, a bendable display suggests a bendable chassis. Not impossible, but cost effectively mass manufacturing millions of bendable electronics are a ways off. A better approach would be to focus more on incremental innovations such as a cover glass-integrated display or waterproofing without making it ugly*.
