What ground? I don't see how you can use drm as an excuse for not putting in blu-ray support when itunes is full of drm.
Actually, DRM has everything to do with this, at least in an indirect way. iTunes is DRM because it has to be. That was the deal that was negotiated with the Big Four when the iTunes Music Store launched. And Apple has gotten a lot of mileage out of that deal by negotiating very reasonable fair usage rights on downloaded songs. But that doesn't mean Steve Jobs isn't anti-DRM.
This article pretty well sums up his stance on the situation.
Blu-ray support for Apple is a far more complicated beast and it still has a lot to do with DRM. Apple has sat on the Blu-ray steering committee since its inception yet they've done nothing about it and it's too little, too late. HDCP
is a form of DRM, yet Apple hasn't implemented it in anything, save for the HDMI output equipped on the Apple TV. Here's what would happen if Apple offered Blu-ray on the new MBPs tomorrow:
1. You'd only be able to use it for BD data and theoretically, disc authoring.
2. Consumers would be very upset that they can't watch commercial BD movies on their new laptops while Sony has been able to do so for almost 2 years. The graphics chipsets might be HDCP compliant, but Mac OS and every Apple display currently manufactured isn't.
It would be a total disaster for Apple if they released a Blu-ray equipped product tomorrow. If anything, I wouldn't expect to see official HDCP compliance from Apple until Snow Leopard. But I'm not holding my breath on that one...
Apple dug their own grave on this one....or did they? Blu-ray simply won't have the same commercial life DVD has enjoyed. Why? The use of optical media for film distribution is becoming obsolete in favor of DRM-protected streaming content. Besides, paying $30-35 for a typical BD title is obscene. And I don't expect to see that change, either. BD will turn into one of those novelties like Laserdisc was.
