Microsoft
Reader is designed to make your onscreen reading
experience as close as possible to reading a printed
book. In addition, it adds active reading capabilities,
instant access to content, and a personal library.
Features include high-resolution ClearType and an add-on
dictionary, as well as the ability to bookmark,
highlight, annotate, make notes and drawings, and much
more. Version 2.1.1 includes a security update that
closes known gaps in the Microsoft Reader security
architecture.
