Being a bookworm doesn’t mean you stick to the classics. Comic books are as popular as ever, and many readers prefer their stories told one colored panel at a time. Today's smartphones are equipped with display screens just as advanced as the phone itself. High pixel density and vibrant colors provide a visually rich viewing experience, and that's a lot of horsepower to waste on printed words alone. This ability to deliver sharp, crisp images in a mobile form factor is a marriage made in heaven for comic book geeks. That's why publishers including DC and Marvel have launched mobile sites and create content specifically for handheld devices.

ComiXology's Comics application works very much like the Kindle app we just discussed. Users can shop around 8,000 of titles from virtually every comic book publisher, with more than 300 being free to download. And once they make their purchase, the title can be read on any Apple or Android device [source: comiXology].

Purists may scoff at the idea of reading a comic book on a 3.5-inch (8.9-centimeter) display (which is the average screen size for a smartphone), but going mobile has its advantages. Storage, for starters, is a big draw for digital subscribers. Collectors couldn't exactly carry an issue around in their pocket until now. And the free app features what they call Guided View technology, which helps guide the reader to the next frame so each panel can be displayed individually.

But where do they justify that price point for Digital Comics? Not worth it. If it were at least half off, than I think I'd be okay with. But the biggest factor going against Digital is there is no secondary market. It's kind of hard to sell this if your book increased in value, which makes having the real thing in your hands more of a sound investment. Besides, I just like turning the pages, turning the book sideways or whatever to look at the art. The feel of it, etc...
