I am new comic reader as well.
Speaking of devices for reading comics digitally, the first thing that comes to mind is iPad. But i find it useless, because I want it to be e-book reader also, but I refuse to read books from LCD screen. (I currently own one e-reader with eInk screen, but I don't use it for comics)
But I think for us, the comic book geeks, there is a lot of hope. The new generation of readers that will use the new "eletrowetting" screen technology. I think it takes one more year, till they are massively on the market with more reasonable price.
