Actually it's nothing that's pulling me off my chair, just because it's not that hard to get digital music without copy protection. But I'm a bit impressed that Apple is actually the first legal music provider to sell music without any DRM system.
Already bought songs can be updated for something around 30 cents, which certainly sucks hard, and the price for new songs can be anything between 69 and 129 cents, a long-time demand of the music industry.
I guess not the action itself is the big important here, but rather the perception of some guys over at Universal or wherever that DRM just doesn't work. No it's finally there: legal, unprotected music ( like in the old days ) at a reasonable price ( not like in the old days ). Welcome.
