I can’t help but think that in the not so distant future we will look at the initial periodical offerings on the iPad with the same disdain we currently have for those CD-ROMs that were all the rage about 10 years ago. Nevertheless, some publishers are trying to innovate. I recently downloaded the Popular Science Application and am impressed. Navigation is intuitive and the multimedia functions are just about right to make you feel like you’re reading something from the future. If Apple releases its periodical subscription service (I’d argue that it is inevitable), I hope some publishers continue to develop their own apps and look for new and interesting ways to deliver content. Either way, as readers, we are in one of the most revolutionary periods since Guttenberg, and I intend to enjoy the ride.
