I was trying to work my way through the rules but stumled upon something that might potentially screw everything up...
The BBB defines devices on p.234 as a bunch of stuff (including commlinks, etc). They are described as smaller than persona sized, creating a distinction between the two icon types. It also goes on to state:
When is a device not a device? When it’s a persona!
Articulating that a device can become a persona and no longer be a device.
When you log onto the Matrix in AR/VR, the icon of the device that you use is subsumed by your persona. It specifically states that there is only one icon, and that's your persona.
When a person uses a device to connect to the Matrix, the device’s icon is subsumed by the persona’s icon, so it’s basically gone from the Matrix until the persona jacks out.
The sticky part, to me, is what happens to the PAN formed from the device that is now a persona as...
Only devices can be slaves, masters, or part of a PAN.
While there are some specific rules concerning the interchangability between devices and personas, it doesn't exist here for all I can tell.
Thoughts?
ETA: I might add, I'm not entirely happy about the whole "the device icon is subsumed by the persona icon" thing in the first place. I think it would make things a lot more sensical if a persona was formed seperately from the device icon.
