That's true, but in those devices can be isolated from the internet by a firewall. Berrylan can't be, or it loses its utility. In order to talk to the app, Berrylan has to send packets to and receive packets from the internet. Also, even after the setup, most RaspPi applications entail having the computer continue to have access to the internet. So the situation is much risker with the RaspPi.
