As an avid Mac user, I don't have any complaints with how Apple is handling DRM - so far. The example given above seems reasonable and allows for at least some flexibility. However, I'm not sure that Apple will have the clout to be dealt into the bigger game that is approaching.
I keep reading articles like [link|http://www.theregus.com/content/6/26528.html|this one] at The Register (where else?) that speak of Windows Media Player-only schemes. I am less worried about Apple driving their own DRM as I am about WMP-only formats. The day iTunes no longer functions properly will be a sad day indeed.
