Thanks to Nigel and Mike for sending me the EPUB version of the book. For Android users, you can view it without converting it if you have the Aldiko reader...and I guess any other reader which supports the EPUB format.
One point to note however....while the book looks great, the number of blank pages makes it really hard to know for sure if your reader's broken or if you're just looking at another blank page. I'll have a go at editing it better....or maybe, Carlos, if you've put together a pront version without the blank pages, you could convert that into an EPUB version and replace the existing one?
