Well, considering that online stores have destroyed strip malls, and online stores are likely going to be destroyed by giant corporations using digital distribution... I guess the trickle effect is worth it. If you outweigh ultimate convenience over a sinkhole in the world economy. To be specific, the United States was clearly based on free-market middle-men who are now becoming extinct, because they can't compete with a 45 minute download vs 3-day shipping. The cost-difference doesn't seem to matter to people, either.
I myself use X-Box Live, and the benefit is I get a demo or trial for just about every game on the market, as well the fact that Netflix and Zune can be installed. So, I can forsee never having to go to a store to buy a game, music LP, or to see a movie. X-Box Live is even going after retro titles, so all my old 3rd-party Nintendo, Sega, and PSX favorites are at my fingertips.
It's going to be sort of like 5th Element soon, where everything is sent to your living quarters, and your basically held hostage by your Internet provider.
Oh, because Lelu was hot... I prefer digital distribution... that's only if women start looking like her.
