We had the some problem evaluating it for our startup. We were planning on using it to deploy ROS in the field and leverage the benefits. I was quoted $20k/year to get started and I think that also included 10 or 20 devices in the field. Then additional costs for that.

There was so many hacks to get it working with ROS since we rely on hardware for robotics to communicate with sensors, actuators, and network. Basically broke the security model to get our application working. We didn't go with it and went Debian as well :D
