Bit like the PDAs have few more functions with the departmental cartridges. pAI is a small role and it is fine as such, yet some extra possibilities for them to do, fitting the frame of a portable synthetic assistant that can’t act on it’s own, would be neat. Or, as Dinarzad says, make it more an actual utility and information tool as it is supposed to be, along with being a flavour/RP little thing, for the present tools for that are limited.
So could it be an idea to try out, to boost the present information tools a bit? Or to add other small things there? I would personally love a pAI that could print out paperwork, take photos and make recordings, that would be a must-have for a detective and probably entertaining for an unit to play. Combat and additional movement capabilities to the chassis mode, no thanks, but information tools, oh yes!
