think "different"
Well, the iPod is a huge sucess. Apple has the highest market share for both hardware and software/content. Now people are talking about PVP (personal video players), and rumors of the next iPod with this capability (ZDnet article). Then they talk about the video equivalent to headphones (another ZDnet article).
This stuff illustrates a fundamental problem with some technology companies, content creators, and nearly ALL journalists. Audio/music isn't video. Period. Yes, video has audio content, but the act of partaking of music is DIFFERENT than partaking of video. Situations are different. Usage is different. Psychology is different. Jobs gets it...he is quoted talking about how people will listen to their favorite song thousands of times over the years, but only watch their favorite movie 6 or 7 times.
As "convergence" takes hold, we are in a dangerous position where people making the stuff don't understand the fundamental crossover points as well as DIFFERENCES between various types of media. This goes along with an arguement I've been making lately that we need to think about having a number of different "platforms" for communicating and entertaining. For instance, the book metaphor is one, and can be realized in physical space as well as electronically (see http://www.nightkitchen.com). The movie/video is another platform or space for creating and disseminating the massage. I would argue that music or the song is another platform, and that is can also contain other elements (meta data in the form on liner notes, videos of the performance, etc). Yes, all the various media elements exist on each, but the central metaphor is different between the three, and as such, the construction, design, and presentation (think devices) needs to be different. Or perhaps there is a "grand unified theory" for media platforms? Not sure about that one yet...but we're working on it.
