"The freedom of a garage band, to record their tracks on a laptop, mix the audio and produce their album. Upload the tracks to a download service and sell their music, send out demos, all without costly studio time."
I think this aspec is always completly over-hyped. My friends got a band, and I've heard recordings done on a laptop - the quality is bad and the mixing is wrong. So how are they going to record a high-quality, well-mixed album? Pay for studio time, of course.
When Napster started god-knows-how many years ago we were told there was going to a new wave of bands who record in their home and find fame and massive audiences on the internet, and it didn't happen. I see nothing in any new developments that is suddenly going to make this true.
