I am a fan of the Communicator form factor in mobile phones, and the Cosmo Communicator takes me down memory lane. It is a clamshell smartphone with a 2-inch display outside that opens up to reveal a 6-inch display and a backlit hardware QWERTY keyboard like a small laptop. Its design is a throwback to the days of the Psion palm tops and Nokia Communicators.

On the inside, however, this is a very up-to-date piece of work. For one, it runs Android Pie, with the option to also boot into Sailfish OS and Linux. There is a Mediatek Helio P70 chipset coupled with 6GB of RAM. Internal storage is 128GB. And for photography, there is a 24 megapixel camera.

The outer 2-inch display is for viewing your notifications. Open the Cosmo up to get productive. There is a fingerprint sensor too for security. Planet Computers, the manufacturers, tout it as “a pocket computer, mobile phone and camera” rolled together in one.
