Articles, which is generally regarded as the best Wikipedia app, has been updated to 2.0. I jumped in after seeing $0.99 limited time offer. Among the new features are "read later" (saves the article's contents for offline read), searching within the article, print, and improved rendering of table. As others have pointed out, the app is certainly beautiful to look at and significantly faster than free apps I've been using (Wikipanion and Wikipedia). But on occasions, its tries to be too clever for its own good: Annoying "shake for random article" feature cannot be turned off. To lock the screen orientation, you need to scroll to the top then pull down (similar to refresh in Twitter and Facebook apps), losing your current reading position. Very tiny button located at the top of the article (requires scrolling to the top) for opening chapter index. To compensate, it has a "double-tap then hold-and-scroll" gesture for skimming the article, but it provides very little feedback and feels strange. "Read later" feature is very handy, but you can only cache articles linked from the current article, not the current article itself. Bookmark uses the search keyword, not the article name, as the bookmark name.
