Opening up iTunes will probably happen one day, and it will probably mean good things like more choices for shoppers.
But this will also help Apple's competition, and allow others to make money from the system Apple has created. So I don't mind if Apple chooses the when and how of it, striking when they feel it is strategic to do so.
After all, the iPod and iTunes are a system that actually WORKS well together, and is designed to do so. The tie is not completely an artificial one.
And the quality and ease of this system is vital to Apple in competing against something that has nothing to do with quality or ease: the Microsoft juggernaut with its deep pockets and existing monopolies in computing... not to mention its own DRM, its own players, its own music software, and its frequent locking out of the Mac platform.
Apple opening up the DRM could actually hurt Microsoft and hurt the iPod both. Is it worth it? I don't know. Maybe someday. For now, I just hope the iPod and iTunes experience doesn't suffer.
I honestly don't think that other players are failing due to being "left out" of iTunes. iPods were big sellers long before iTunes was selling music. I think--and this may be crazy--that other players are failing because the iPod is simple to use and well-designed. And also, now, because the iPod has built up name recognition.
Someone else could design an integrated system as good as iTunes and iPod, and seize market quite nicely. But if they don't--and so many have failed--then I'm not sure why Apple should be forced to help them.
As for the consumer, ANY DRM sucks.... but it's the record companies, not Apple, who demand it. They would never have let iTunes happen at all without that. At least Apple's DRM is far more liberal than any non-piracy use I might personally have. (Except, that is, for splitting the iTunes/iPod system. Which I don't want--no other players are so good I need to have them--but I can understand that some do. Although maybe those people should be wishing for new software that's as good as iTunes and integrates just as smoothly with those other players.)
I do agree that I should be able to do what I want with my music, ideally--but at least I KNOW up front that I can't use another player, when I buy from iTunes. I have the choice to shop elsewhere (good ol' CDs) if I don't want to buy into the iPod/iTunes systems. I am not being tricked into anything.
One thing I can see Apple doing--when the time is right--is allowing other companies to be Fairplay-compatible (and making some money from them for the privelege) but NOT integrating other players with iTunes (beyond what they already do with synching playlists of CDs ripped to MP3). Not integrating them to the level of calendars and contacts and games etc.--so that the iTunes app is unaffected and does not become more complex or buggy. Let people synch m4p AACs but go no further. And Apple could then tout these other non-music iTunes features as selling points for iPods.
