The notion of providing a digital copy for portable watching is one of the selling points for many commercial Blu-ray titles, but unfortunately the reality rarely matches up to the marketing hype.
As Nick over at Gizmodo explains in a lengthy and entertaining piece, his attempts to access the digital copy of Zack And Mimi Make A Porno suffered twin blows: the digital copy won't work at all on a Mac, and even on a PC it comes with so many restrictions, it's very hard to resist the urge to download a functional torrent of the movie instead.
Judging by the comments over at Giz, the most common commercial solution to this dilemma is to offer a digital copy via iTunes. While that solves the Windows versus Mac issue, it doesn't provide much solace if you don't use an iPod. (Sure, you can argue that's 80% or more of the market, but that would also apply in a Windows-versus-Mac scenario.)
