Why should you care about what Trent Reznor has to say about Apple or smartphones in general? Well, for one thing, the front-man for Nine Inch Nails is a digital music visionary who's gone it alone and found gold in the deep coffers of the Internet. And that little device in your pocket just happens to be the future of mobile computing and converged media players.The story begins last week when Apple rejected an update to the official Nine Inch Nails iPhone application on the grounds of "objectionable content" (read: too many F-bombs). In this case, as it was in the rejected Tweetie update , the offensive content isn't actually part of the application; Apple's concern is with the song "The Downward Spiral" that can be streamed to the updated NIN iPhone App. The stupidity of this is palpable, but the hypocrisy is best described by Trent himself in a forum post over at NIN.com. Steel yourselves: unlike Apple we haven't censored the material -- so if naughty words can hurt you then by all means, don't click through to the full quote after the break. But Mr. Jobs, old pal, if you're listening... Trent may not be Bob Dylan, but he is the voice of the digital music generation.
