Some good points from the Monday Note blog about the first forays into iPad apps by print publishers: http://www.mondaynote.com/2011/01/02/ipad-publishing-time-to-switch-to-v2-0/
For sure, no one has hit a home run yet. The Economist is certainly among the best examples and I like the Sunday Times app for price and convenience (although the constant logging in for the app and web content is incredibly irritating). But the number of affordable tablet devices about to flood the market is going to make iPad style devices a compelling platform on which to build and experience exciting content. Innovative apps like Flipboard are just the beginning of what I still think will be a revolution in publishing.
