Its special magic is, when you're reading a Wikipedia article with it, and you tap a link to another Wikipedia article, it just queues that up and downloads it in the background. I find it exactly right for reading a topic article that makes me want to read more around the topic, I can stay focused on one at a time and let it keep track of the neighboring topics I want to get to.
LoboWiki is a great reader for wikipedia. Its great for reading a quick bit before sleeping.
Had no idea Wikipedia had such a good official app...
Almost as good as LoboWiki...
