Carry over 450 comics in your pocket with the Comics iPhone App (free). The app comes with 70 free comics and uses the new, in-app purchasing system so you can browse and buy hundreds of comics from nearly two dozen publishers, including Marvel, for $2 each. Once you’ve selected a comic to read, the panel views flow naturally, simulating how your eye would move across the page. You can also zoom in on any image, or rotate to landscape mode automatically to get the best fit for each panel. Download it free from iTunes.
