While previously we planned to publish our ebooks in at least three different formats – pdf, prc, and epub – we have reached a decision to stick with the two specifically ebook formats and drop the pdf. The reason is fairly simple: both prc and epub files can be used on any PC or Mac, on any OS. If you check our FAQ section, you will see some hints as to which e-reader applications we recommend for your computer, but if you have any further suggestions, please share your ideas with us and your fellow readers.
PS.: Stay tuned, we are about to release our first ebook soon!
