FYI, one small bit of errata that made it into the German Rigger 5:
Drone Cyberarms now have a capacity limit of BOD x 2 and the possibility to give them Synthetic arms is explicitly mentioned, with those having a cap of BODx1 for Drones.
And since there was occasionally the discussion whether only the UP cost for armor would 1 UP for the first 3 Armor and then 1 UP for each additional, its now explicitly stated as "1 UP for each 3 Points of Armor"
