To my understanding theres only 3 devices that can traditionally accept a persona those are RCC Commlinks and Cyberdecks
Agents are like programs but more and can only be incorporated into devices that are able to run persona firmware
Drones traditionally dont have agents but pilot programs that act like agents
A pilot program is specific to the device it’s in. You
can’t just copy a program from one device and move it
into a different one. After a week or so, the pilot is so
adapted to the specific vehicle, drone, or other device
that it’s useless in anything else, even other devices of
the same model.
