@xanthiss: It depends on the book. Digital only comics are generally less. The DC titles are the same price on release, but usually drop $1 once the next issue comes out and the New 52 #1's are all $.99. Marvel titles seem to stay the same price, at least for a few months.
I've been looking to move to digital once I finish the back log of paper comics i currently have. I've bought a few and really enjoyed the experience on my Kindle Fire. Reading them on my smaller smartphone isn't all that great, but that's part of why I looked into the 7" tablet market. I wouldn't mind this as it gives me both options at the same price rather than spending just as much for the digital copy. Is this Marvel comics app tied into comixology (Like DC) or a Marvel standalone app?
