So the news is
that Amazon haven't updated the Kindle app on the iOS platform to support comics?
DC Comics, home to Superman, Batman, Wonder Woman and Watchmen, has started to sell individual issues of its comics on Amazon's Kindle, the iDevice menagerie and the Nook e-reader. DC has previously sold graphic novels on the three electronic bookstores, but only offered individual issues through third-party apps. The comics …
The only rule is that if you sell content in an external store then EITHER you make it available for purchase at the same price inside of the app (at which point Apple gets its cut) OR you're not allowed to link to the store from inside of the app. Kindle works the second way on iOS. You can buy stuff on the Amazon web site, but there's no link to it from the Kindle app.
I'm not sure why anyone would want to use Kindle etc for comics anyway. Comixology's app is much better with the "guided view" feature that zooms and borders each panel in the comic book. Plus all the comics are scanned at a high res now so iPad 3/4 and Nexus 10 devices get really sharp looking comics. Then of course there's the selection on Comixology which is absolutely massive with hundreds of publishers on there.
I'm off to read some more Avengers...
So far the only individual comics (of DC) available on the Nook are the ones people have scanned and offered for sale. Finding comics for the nook at nook.com is not easy. The fastest way is to type in "Arts & Entertainment" and select Newsstand. The comics SUBSCRIPTIONS start about the third page.
. There are Graphic novels available.
FOR THE NOOK, the comics stay on your Nook until you delete them (or your Nook gets deleted). They still exist in your online library. There is a Nook application for the PC. You can read your library from either device.
If you found a way to print them, the publisher would be upset for sure.
So, yes, you OWN certain rights. There is an option to LEND but I haven't used it.
