Simply getting the news is not enough – your news source should also not be horrible looking. The CNN app has long failed on that second count, but now it has a shot at redemption. CNN has updated its app with a Holo UI and support for multiple screen sizes.
The updated look has a proper action bar and a grid layout of stories. I'd hesitate to call it card-based, but it's close at times. The interface scales appropriately to tablets now, and CNN has removed the "for phones" modifier from the app's name.
Users are a little torn on the quality of the new update. Some complain of bugs and sluggish performance, but others are relieved to be rid of the old dark UI (which you can see below for comparison). The update is still rolling out, so you might get the old version if you install it now. Be patient.
