Region codes aren't a problem that DVDs <i>must</i> have, though. I've seen region free DVDs (admittedly, this is rare), and as you've already mentioned, there are region free DVD players. They're a bit more expensive than regioned players, but the average American is unlikely to need the feature any time soon (and if they have a DVD player on their computer, and some technical expertise, they don't really need to purchase a region free set top player).
All the region-free DVDs I have are bootlegs. ^^; Well, except for one, which is kind of an oddball.
In any case, you mentioned that The Average American is not likely to need a region-free player, which I suppose is where I admit ignorance. From an international standpoint, we need those region-free players.

I've never had a problem with a DVD wearing out. There's no reason why a well treated DVD can't last for fifty or more years, assuming something doesn't go wrong with the formula of the plastic.
I've watched my Pulp Fiction DVD about as many times this <i>year</i> as I've watched my original VHS copies of the Star Wars trilogy total, and my Pulp Fiction DVD is perfectly unharmed. The Star Wars trilogy looks like crap now, and the magnetic tape is wearing out.
Constant use aside (I have no issues with DVDs lasting a heckuva lot longer than VHS that way), DVDs have turned out to have a shelf life of maybe ten years or so, just a bit over that of VHS tapes. 'Twas a story on Slashdot one day, and the reason was
exactly because of the formula of the plastic or some such. Basically, an inherent problem with DVD manufacture in general. DVD manufacturers alternately admit this or deny this strenuously, so Your Mileage May Vary.
But I digress.
In any case, I have nothing against ebooks per se, especially if some new utopian means of energy production allows us to have nice clean energy to power the readers, and save trees in the process. But discussing it now is a bit premature, and probably due to the heat, hunger, and gold.
