What I wonder is about the Elder Wand... I mean... I thought it was supposed to be undefeatable but it can only be passed down by defeating the owner? Huh?

Undefeatable in a duel. But Grindelwald stole it. Dumbledore handed it over to Malfoy. So apparently you have to win it by something other than a straight-up duel. And that's the point, I suppose: there are things stronger and more effective than the pure force that the Elder Wand represents.

Except that Dumbledore won it from Grindewald in that famous duel right?

I think it is more like The One Ring. Remember the often quoted line, "the wand chooses the wizard." So it sort of chooses when it is getting passed on by letting the wizard lose. Then again it makes sense that it is something other than a duel, based on the children's story. That was the whole moral of it, that a stand up fight is not the only way to die (or was it something about boast). If that is the case the Grindelwald must have let him win... but if that was the case would the duel be that famous? I guess so since both parties in the duel were already (in)famous by then.
