There are a few things that I have heard people saying that I would like to challenge by adding my two cents to:
1: Apple has a monopoly: No it doesn't!!! It's not even close to having a monopoly in either the music download or music player side. There are dozens of players and dozens of places to download music. This argument has absolutely no validity.
2. It provides people choice: Come on...does Real "Real"ly offer anything that people want and/or iTMS doesn't have?
3. It will spurr iPod sales: Maybe 2 or 3 but the bigger concern is if labels start to get spooked as Real begins licensing out it's Harmony software and pull their tracks from iTMS.
4. How good is Harmony: The only way Steve was able to get support from the industry was by creating a hack resistant codec. If Harmony is easily hackable, which it probably will be, then see #4.
Well that's about it for now.
