Looking at how they it handles on the PSP I have to say that it's not very appealing to read a comic in this format. Just like Ryan said there are other devices like the iPad or the iPhone which will probably be more attractive.

I think its neat, and good for portability and you wouldnt have to worry about damaging the book itself.  But I would never give up the paper version.  I am a collector and you actually get to really appreciate the art and the story so much more.  I am old school and would never go digital exclusively.  It takes away from the magic of the actual book and the collecting. 

I don't think reading comics on your psp will replace reading a hard or soft book but i think if you are a gamer/comic reader and you travel quite a bit i think it is cool to have a few comics on there just to have a nice collection to read without carries a big device or a pack of books around.

if you buy a comic by dc for you psp you can read it other paces as long as you have a comixology account. If dc said as long as you have a account you can read their comics on a i-pad i-phone or psp or computer through the web browser

I'm totally about to get this on mmy ps3.
