Oh okay, definitely! But I don't think anything like that will go from fruition to dominance, (I personally prefer buying physical music; CDs and vinyl through a good stereo far exceed MP3s, and I actually have both) to digress a little: I don't think the music and movie industry necessarily want to shift in that direction, or at least they're reluctant to permanently alter their business strategies. Backlash from DRM and rampant piracy doesn't encourage incentivizing digital distribution. And I suppose the kicker is actually when you get an immediate download upon ordering a CD, or a DVD and digital copy with Blu-Rays, or Portal 2 on PS3. That's what I want to see more of. I guess that type of service isn't really feasible by all businesses.
For software, which is birthed for and lives exclusively on computers, there is nominal difference between physical and digital distribution. It's always been part of computers, so it's a natural evolution to be able to purchase and download and install it directly with no physical middleman. I don't feel like a digital purchase devalues the game. Same software, no casing (admittedly I like to proudly display my game cases).
My problem with music and video distribution is there's currently not a constant service level from what end you obtain. Therefore you have this awkward three-tiered distribution paradigm. You're not guaranteed the highest quality for price in ether digital or physical purchase. Most of the time there seems to be an okay parity, though. You can get both from piracy. Piracy is free and illegal and you're also voting "no" to the producers by not purchasing it, which potentially means less of that type of product.
It's an interesting topic worthy of discussion, not to derail the thread though. Pretty tired now /night
