I have a new Ipad and have been using Ibooks, but curious if Kindle for Ipad is better  (ie better selection/price) or if that app might open up library options for me? Any thoughts??

You need to read the other Topics Both here & on Amazon!  Apple is BLOCKING or Raising the costs to its user to put Kindle/Nook eBooks on iAnything!   They want iOwners to Only buy from them I think!  But I not techy LOL  And dont keep up on it too much. 

If I have a choice between IBooks and Kindle, I'd chose Stanza. ;  )

Stanza has a better interface for me, I can set tags in Calibre and they get sorted that way by Stanza, and I can load directly from Calibre to Stanza.

I've never liked iBooks, and will read off the Kindle app first rather than iBooks.

Apple is BLOCKING or Raising the costs to its user to put Kindle/Nook eBooks on iAnything!

So far, not blocking, and not raising the costs to the consumer. Basically, you can still buy stuff online and download books to various eBooks Apps. You just may not be able to buy while in the app. Depends on how it comes down between Apple and Amazon.

Apple could pull the Kindle App if they wanted to since it's after the deadline. I don't see them doing that at this point, though. I think if anything changes, the Kindle app will just remove the Amazon "buy it now" link and the fight would be over. Apple can't take 30% of a sale if the sale never happens.
