Epiphany that struck me last night: Sauron made a horcrux.
Stick with me here: the One Ring kept part of the spirit of Sauron locked inside it and because of that, Sauron didn't die when Isildur nicked his fingers off. Sauron went on to live a very Voldemort-like existence as mere shadow hidden away in a dark forest regaining his strength. The ring, meanwhile, went on to shrivel Smeagol into Gollum (Dumbledore's shriveled hand, anyone?).
Now, in some ways Sauron made a far better horcrux than Voldemort. The ring not only corrupts the person who carries it; it also has a mind of its own. So unlike the horcrux stolen by RAB which is idly hanging about in the attic at No 12 Grimmauld Place (at least my best guess is that the locket from OotP is RAB's locket), the ring actually takes steps to get back to Sauron. Mind you, the ring is in no hurry -- a bunch of years hanging about in a river, 500 years snogging Gollum, 60 or so years snogging Bilbo...and then it finally decides it's time to kick it into high gear. Granted it was waiting for Sauron to be in better shape, but that's a really really long time to snog people.
How much better would Voldemort's horcruxes/horcruces have been if they were programmed to find him? Yes, I know the idea of Voldemort's horcruxes is that they are spread out to minimize the probability of them all being destroyed. But Voldemort has no idea if his horcruxes have been pilfered by disgruntled Death Eaters or arch-enemies. Wouldn't it be better to have some sort of alarm? Like a lo-jack for your horcrux? Or at the very least, something like Sauron had and the horcrux would want to get back to Voldemort.
Voldemort does get points for creating more than one horcrux. If Sauron had created an entire jewelry collection (The One Ring, The Two Earrings, The One Necklace, The One Anklet...) and poured his malice into them, it would have been nearly impossible to kill him. Can you see Sam and Frodo on Mount Doom tossing all that jewelry in? Moreover, can you see Frodo wearing all that jewelry? ("You look very pretty in that tiara, Mr. Frodo, and no mistake.") Or worse...Gollum?
So in the finally tally, I'm going to give the win to Voldemort. Because he knew the value of not putting all of one's horcruxes into one basket. So even if Harry picks them off one by one, there are still more chances for failure on Harry's part. That is, if Voldemort ever bothers to check on his horcruxes and doesn't find out during the last confrontation that he has none left.
Harry: Ha! I've destroyed all your horcruxes and now I'm going to keel you!
Voldemort: OMG, you know what a horcrux is?
Hermione: It's horcruces.
Voldemort: I see you brought your grammar Nazi with you.
You know what's really, really sad? I started this post at 8am this morning and am only now finishing it. So hectic.
