The iPad cometh

Apple introduced its much-anticipated iPad today.

Bells and whistles aside, the biggest news for digital marketers is probably the shot it fires across the bow of Amazon and the Kindle. Apple will introduce an e-book store, iBooks, which it is probably hoping will be to the iPad what iTunes was to the iPod. (That's a lot of "i"s.)

It also promises an improved user experience for online news and video — which could potentially affect how those media are sold and how ads with them can be interacted with.
