Modular design is the coming thing in smartphones... at least it is according to LG and Motorola Lenovo. But what about smartwatches? At least one group seems intent on translating the idea to wearables. The BLOCKS design uses a conventional smartwatch body that houses the primary screen, battery, and SoC, but adds extra functionality via modules that snap into the body like links in a metal band. It's a lot like the Project Ara idea, but integrating the modules into a functional band makes for a surprisingly elegant product.
