For reading newspapers and magazines, I use FeedlerPro in combination with Readability, and to a lesser extent, Instapaper. Another reader I kind of like is Reader X, but it's still in its early days so a bit buggy.
For drawing, you could check out Papers, Noteshelf and 123D Sculpt.
In general, it just comes down to what you use it for. Among other things, I read lots of pdfs (iAnnotate, GoodReader), listen to podcasts (Downcast), listen to local radio, use Twitter (TweetBot), blog (WordPress), take notes (Evernote, Notability, 7NotesHD), do outlines/ mind maps (iThoughtsHD and Cloud Outliner), record meetings (Voice Memos) and mediate (Insight Timer).
