Robert Capps wrote an interesting article for Wired called "The Good Enough Revolution" that was published in Sept. 2009 Edition of the North American version of Wired magazine.
"What consumers want from the products and services they buy is fundamentally changing. We now favor flexibility over high fidelity, convenience over features, quick and dirty over slow and polished. Having it here and now is more important than having it perfect. These changes run so deep and wide, they're actually altering what we mean when we describe a product as "high quality"."
This is what makes mp3s better than CDs. This is what makes DVD better than Blu-Ray, and instant netflix streaming videos better than DVD. This is what makes a 3 megapixel digital camera better than a $5000 35mm film camera.
This is what makes digital streaming over the internet better than physical, tangible objects.
