Adobe Reader gives you access to all types of PDF documents. View, print, navigate, sign, and comment on PDF files, including forms and multimedia. The commenting tools allow you to highlight parts of the PDF file and provide feedback on it using the Sticky Notes tool.

The user interface for the latest version of Adobe Reader has been simplified. Select the reading mode that best fits your screen and your needs. The search feature quickly finds text, no matter where it is in the document. Use standard keyboard shortcuts for printing, zooming, and finding text right in the browser. You can also play back embedded multimedia files in a variety of formats.

Though some users report instability with Adobe Reader, it is one of those programs that seems essential to Internet life. However, the latest X version does not support Windows XP, so XP users will have to stick with version 9 or find another reader.
