Keith>You actually, can blame this either on TEI or EPUB, but on the tools or how you used them. I can not say which! Not sure what you are saying. I think you are saying that TEI *could* be used to generate attractive output on small devices, but that isn't being done anywhere today that anyone can show me. Most EPUB I see *does* generate attractive formatted display. Granted some EPUB comes from paper houses which "don't get" EPUB and their stuff can be pretty ugly because a small electronic device *is not* a sheet of paper and paper design rules don't necessarily translate directly to electronics (part of the reason PDF really doesn't work on small devices -- small devices are not made of paper.) A proposed "master" format should be able to successfully demonstrate the entire food chain, from raw OCR to rendered text on an end customers' tablet such that they say "Now *this* is a book!"
