Is this even possible? I don't have an iPad (yet) but I know when I do I'm going to significantly try out reading on the thing. one concern I have is which ebook app to use, ibooks, kindle, barns&noble, or any of the other dozen such apps. The main differenting factor I'm thinking about is price. The same book may be $20 on the ibook store, $16 on B&N, $15, on Kindle, and free on one of those knockoff apps. I'm a frugal guy and I know I will check every single store comparing prices (at least until I want to shoot myself or I determine one store that is always cheaper) Another concern I have is if I do end up buying some books in ibooks, some in kindle, etc, it will be difficult to remember where I bought which book. So basically I want an app that can do two things. Query all the known/popular ebook store and display a list of them comparing prices. And then show all your purchased ebooks from all the different apps. Then when you click on one it will automatically take you into that app. Thoughts?
