Here's a BW Online special report on how Apple could fall. I can't imagine that Apple, for all its genius, will be able to dominate mobile music (and to a lesser degree, entertainment)the way it does today.
That said, my old suffering screen-shattered iPod finally died a couple of weeks ago, and I just bought a new video iPod. This convinced me that video is seriously going mobile--and that we should hurry up and develop good v-podcasts for this site.
Sorry I've been posting so little. I have a big project that I hope to get into the magazine this week. More about that later. (Yes, on that side of the biz, we're still as secretive as ever.)
