Mecha Comet is a modular, handheld Linux computer with snap-on extensions

This is not a phone. The Comet by Mecha Systems is a modular, Linux-based handheld computer built for hobbyists, engineers, students, artists and roboticists of all kinds. The Comet is a chunky palm-sized device, and it has a 1.8 GHz ARM64 Quad-core processor, 4 GB of memory and 32 GB of on-board storage, though this space is expandable. Most of the Comet's features are customizable, in fact. The Comet's magnetic snap interface allows users to clip on a variety of control panels, called extensions, transforming the handheld into whatever device you need.
