Amazon's current specs state that they require 300 ppi or better. And I'm pretty sure that I read in multiple places that B&N and Apple want a similar quality, but those instances are hearsay, I haven't looked at any specs other than Amazon's since I created my first set of images last fall. Unfortunately, Amazon's image specs are ambiguous and contradictory, so it's hard to tell what they really want and what they'll accept. I figure if my images satisfy Amazon, then they should be suitable for the others.
