On Michael Gartenberg’s blog he shares a problem many of us have had with DRM’ed ebooks (Microsoft’s .lit format in this example). Once you buy these there are all sorts of wacky activation issues, limited number of machines you can have supported, and the experience, even for the enthusiast is often the opposite of what you’d want in an ebook experience. He points to a good solution (Amber LIT) that exports the .lit files out as PDFs. [via] Link.
