In its review, CNET draws comparisons to NYTimes [App Store, Free], a competing app released by The New York Times last August and significantly updated to version 2.0 just last month.
For one thing, the Journal app seems to load much faster than the notoriously pokey Times, and it sports prominent buttons for Video and WSJ Radio.
The latter consists of a two-minute podcast that starts streaming immediately when you tap through. But it lacks a time stamp, so there's no way to know without listening if it's any newer than the last podcast you played.
As for the videos: they flat-out refused to play, though we'll cut the app some slack on its first day; no doubt looky-loos have stampeded the Journal's servers.
