I've looked at two of these teasers from Penguin and I have to say I really don't like the way they look. The text in these is not fully justified when displayed on my PC and, even if it was,
it wouldn't be when displayed on my Sony Reader. I seriously doubt that I'll be paying money for books in epub or Adobe DE formats even though I am quite interested in what Penguin often publishes. Books should be fully justified and the Reader firmware should be improved to support that, too.
