From the TechCrunch piece “iPad mags need a new blueprint“:

"Replicating a dead-tree publishing model on a touchscreen is a recipe for obsolescence."

As in, don’t just throw PDFs on the iPad and call it a day. Also:

"…subscriptions are not going to save the media companies. In fact, they’d be smarter to give the apps away for free and make more money from the advertisers, who want to reach as many people as possible. The ads should also be worth more because they just look better in an app where they look more like a magazine ad and can take over the whole screen when tapped on."
