The 2.5 MB application is described as “built from scratch as a lightweight application that takes advantage of the internet.” The software works both with and without an active internet connection, and supports publications in PDF and XHTML formats.
A number of free publications and excerpts of publications have also been published that can be reviewed through the application. Adobe seeks feedback on the program from users so that they can refine it with a view to publishing the final version.
According to the developer, it is a complementary product to Acrobat Reader, noting that this software offers a number of features that are most useful for e-book readers.
