I barely know the show, and all I have to go on is the films here, so bear with me.
How quickly do Borg assimilate people? And exactly how do they do it? I remember in First Contact they needed to inject a little proboscis in to people, lead them away to deeper in the ship, and started transforming them in to drones. If they need to be outfitted first before combat, they're not gonna make for very good soldiers whilst in the middle of said combat.
On a side note: in First Contact, where did the Borg get all that equipment? They beamed aboard the Enterprise and suddenly a whole bunch of their equipment appeared with them in the decks they took over. I've heard that doesn't make any sense, that they can't conjure equipment and materiel out of nothing.
On that, how fast can they assimilate technology? I know the big argument is that they'll "just assimilate", but what's the time like on that? Do they have an... assimilation wave that instantly makes everything theirs, or is there time required? It seemed to take a while before they realized that Data was beyond their reach. And again, that's technology and physics that exist in their own world. What's it going to be like for them to deconstruct and understand technology (which, frankly, is full of bullshit and nothing short of magic) and physics that don't comply with their own? I don't think they can just touch an alien (in every sense of the word) technological construct and master all use and understanding of it, Matrix-style, and then actually integrate it with their own. I also still want to know what the range/limitation is like for the drones' adaptive capabilities; I don't want to shrug and just say "no limits" for either them or Star Wars' blasters and sabers.
I have no idea what those 39 ships were like, so what that f*cking up was like at the hands of one cube is beyond me. I want to know what it'll be like for a Borg cube to fight (and I quote from lowly Wookieepedia here):
7,000 Starfighters
4 Strike cruisers
3,600 Assault shuttles
I have no idea what those latter ships two are.
