Adobe Acrobat Reader is not the only PDF reader

If you thing Adobe Acrobat Reader is too slow and too complex, then you should try Foxit Reader.

Advantages, taken from the manufacturer's web site (excluded are characteristics of non-free version):

• Incredibly small: The download size of Foxit Reader is only 1.5 M which is a fraction of Acrobat Reader 20 M size
• Breezing-fast: When you run Foxit Reader, it launches instantly without any delay. You are not forced to view an annoying splash window displaying company logo, author names, etc.
• High security and privacy: Foxit Reader highly respects the security and privacy of users and will never connect to Internet without users' permission. While other PDF Reader often silently connects to the Internet in the background. Foxit PDF Reader does not contain any spyware or adware.

In a couple of months using it I had no complaints yet. Available are also versions for Windows Mobile, Embedded Linux, Desktop Linux, and even U3 USB flash drives! If you need it, it also integrates into your web browser.
