Hm, I am afraid I'm a little slow tonight ... I can import thousands of books but only see one? What would I do with all the others then?

Just recently I thought that limiting the number of books would be the only way to have a trial version that shows everything the app can do. So I guess that makes sense (just that I'd find it hard to explain why exactly the iPad version is free and the iPhone one isn't, but that's a different topic ..)

In any case, I also think the descriptions in the App Store should explain the difference and the limitation of the paid app. The German version doesn't do that either, it doesn't even tell you there is actually a full iPhone app available. There is only a mention of a "free and fully functional" iPad app.
