Up to now I have been publishing e-books using DeskTopAuthor. The end result you can achieve is quite stunning and there are lots of features available, but the market is rapidly shifting away from PCs to hand-held readers and mobile devices. So for many months, since ePub was made standard, my task has been to find suitable ePub creation software (as I am not an XML/XHTML wiz) and an open reading device on which to test the results. I have found eCub and Feedbooks both very helpful and I am tempted to buy the BeBook or the CyBook reader.
Any feedback would be welcome.
