Any apps just get updated and improved? Here are a couple I use that impressed me. 1. Evernote. It has had horrible issues every since last summer, when they implemented rich text support. Although this build still has occasional lag with typing for some users, it is a marked improvement over the last update, and it is definitely headed in the right direction. 2. iAnnotate. Massive overhaul to the interface. Now I can finally say that it looks user friendly. I have only played around with it a little bit, but so far I am quite pleased. In my informal tests it is the fastest to render pages (compared to GoodReader and PDF Expert), and it is definitely the one with the most features.
