Thanks to a wonderful Xmas gift last year, I have been catching up on a decade and a half of missed comic books without the frustration of the actual books. Marvel's Digital Comics have thousands of digitized comics, all laid out for enjoyment. And Marvel has introduced version 3.0 of their reader, which has made the experience far more seamless and rich.
I still dislike the gaps in the issues, and the difficulty in reading the crossover events (would it kill you to index the Civil War and Secret Invasion series, folks?), but this reader is a definite improvement. Now, Marvel, make me an iPhone version, and we are seriously talking. Hey, you already offer issues for sale for reading through Comics X on the iPhone; can you just extend my subscription to those?
