There are plenty of news apps for the iPad, but I'm happy to see USA Today aggressively improving what was already a useful and easy to use app.
Version 2.0 is still free, and it has added more extensive tech coverage. Tech reviews feature iPad apps, and there is a video player, along with a spiffy This Week in Space section. The app has also increased travel coverage, along with a map that displays airport delays.
The app now multitasks in iOS 4.2, and the developers seem to have squashed a nasty crash on startup that many people were seeing.
