The program does all the author claims it does and it has more
features (last I checked) than any but ReaderWorks Professional.
However, it doesn't use the standard MS E-Reader. Instead, this
product uses the IE5+ browser in a special wrapper. There are
advantages and disadvantages to this. Also, creating e-books with
any software was/is surprisingly more difficult than I had imagined.
I'm working on clips with NoteTab Pro to help make it easier for me
to convert web pages to e-books. His price for the software hasn't
changed in 3-4 months, although the web site claims it is a short
term opportunity. Whether it meets your needs or not is something
you'll have to decide.
