I haven't done any deep research, but it seems to me that most Forumites say how much they have enjoyed ebooks, not moaned about them.
Now moaning about Readers, that's a different ballgame, but even so I think most are happy with them.
But if there is a problem with them, it's good there's somewhere to enquire/find solutions/what one suits best, etc..
And where better than here, in a community of hugely varying interests, skills, talents and knowledge.
