The ABC News iPad app opens up with a neat-o user interface: a globe that you can spin to select stories, or shake to randomize content. It'd be easy to dismiss that globe as mere gimmickry if it didn't actually make getting the ABC News content you want -- by topic or favorite news show -- easy and intuitive. Sharing (via Twitter, Facebook, email) is baked right in, as is a "My Favorites" feature that lets you save stories for offline viewing.
Half a million iPad users have already downloaded the ABC News iPad app, and we suspect a lot of them, upon first using it, said something along the lines of, "OK, that is really cool." (We sure did.)
