What do other stations have that we don't?

[Wraithcraft]

better (existing) ghost roles and choices as well as ways to get back into the round (tg has replica pods, positronic brains and pAIs for one thing), 

I randomly read wikis for other servers and this just seems like a fun way to get ghosts back into the game.  Ghost drones are fun, but sometimes you just don't wanna ghost drone, ya know?  I always wondered how neat it would be to be a mini-helper for someone.

what do personal ai's do exactly? Can they do all the usual ai things but like with the pda as their main camera or is it just like an RP friend

They're like an RP friend. They act like a PDA, and they can fit in your pocket. They can download a few programs, like one that lets them view security records, one that lets you view medical records, and arguably the most useful one, one that lets the pAI hack open doors. They can also turn into mini robots and scamper around.
