Phonebloks
From Just Solve the File Format Problem
Phonebloks are still vaporware as of this writing, without even a Kickstarter-like funding campaign in progress yet. It's an intriguing idea, however; a mobile phone/device built of modular components snapped together Lego-style, to make the custom device of your choice, upgradeable or repairable by replacing obsolete or broken parts without having to discard the rest. It's more customizable for the user and better for the environment.
