Centering is probably most useful to get rid of pesky dice pool penalties. Even if the situation doesn't give penalties itself (such as range, reach or bad visual conditions), do a Called Shot for extra damage or effect and negate the drawback.

Doesn't actually work very well - Calling a shot is a free action, so is Adept Centering, so you can't do both - or rather, you can, but it eats a Simple Action, and that's very often not worth it.

Then why couldn't anyone else have done so? 

Who's to say they haven't? K-10 plans "leaked" out, but who knows what K-11 is or what the competitive companies have produced in there R&D labs.

Hm, forgot that. Kinda sucks... Still, you'll get some kind of penalty more often than not, so I'd still consider Centering worth taking, provided the gm doesn't make it too hard to center. Mages get much better deals with metamagic than adepts... Which is why I'm heavily in favor of the PP metamagic optional rule.

There are plenty of ways an adept could theoretically "not even know it", but they don't make sense for Batman, who after all didn't fall off the turnip truck yesterday.  I could see it if you were porting Shadowrun rules into the Batman universe, but I don't see it if you have Batman in the Shadowrun universe, where the existence of magic is well known.

Adept is the only way you can really go if you give Batman the same attitude about keeping himself "pure", since magic is not really something you can choose to have outside of the metagame of character creation.  Hell, if you run with some of Frank Miller's imagery, you could easily give him a bat-aspected mentor spirit of something like Dragonslayer or Wise Warrior.

The trouble with an unaugmented mundane is that Shadowrun has hard limits that such builds smack into.  In the comic books, if Batman ran into five or six cybernetic thugs, he would kick the crap out of them, because he's just that damn good.  In Shadowrun, his Agility caps out at 7, as does his skill, so assuming a specialization, he is rolling 16 dice for his asskicking.  Good, but there are starting augmented or magical builds that could absolutely own him in combat.  Yeah, you could give him a suit that is the equivalent of military armor with far less bulk but all of the special accessories, and lots of nasty chemicals in his trusty utility belt, but ol' Bruce never seemed to rely on that stuff - it supplemented his superhuman natural skill.

Sorry, I might've been unclear or have misunderstood myself.
It just seemed to be like a lot of people said Batman is a mundane 'cause he "obviously" isn't magical (and I guess they use the only reference there is, the comics written about him now).
I just wanted to say that he can be magical without losing "what makes him batman". And saying that for all we know, the batman we know (from the comics we know) is magical, the entire world, including himself, is just completely unaware of it.
For completeness, I have to point out that just yesterday I finished playing Arkham City. Seeing some of the things he pulls off in that game, combined with all the time I spent reading SR books, really makes me believe that Batman might be an adept.
In the SR world, he would be aware of the fact that he's an adept. But he'd also be smart enough to keep that fact hidden. (And trained/initiated enough to be able to do so with Masking, combined with Flexible Signature to hide his real identity.) Sure would explain why he can so frequently beat augmented, genetweaked or otherwise 'superhuman' enemies.

[Leticron]

I'd say adept with masking and flexible signature would suit his nature.
I do not see him being augmented though. Given the differences between the Batman universe and the shadowrun universe he couldn't be unaugmented & mundane and kick ass. This whole "overcome your fear" thing points in the adept direction though.
