"Simply plug your phone into an HDMI screen, connect up a keyboard and mouse, and you’ve got a lightweight desktop experience you can take anywhere."
"Want a complete desktop experience on your smartphone? Then take a look at the Maru operating system"
"Today's Android devices have plenty of RAM and viable processors: How great would it be to present the software directly on smartphones on an actual Debian system? Maru OS makes this a possibility."
Maru automatically detects when an external display is available and spins up your desktop. It boots in less than 5 seconds.
Any Android-compatible bluetooth peripherals will work with Maru.
Gotta run? Disconnect from your screen and Maru will preserve your desktop state in the background so you can pick up right where you left off.
