I sometimes think I spend half my working day reading PDF files of one sort or another. Foxit Reader has lowered my blood pressure substantially by eliminating the lag waiting for Adobe Reader to load. I still use Adobe Acrobat when I need to create something complex, but otherwise I’ve set my defaults to use Foxit Reader to open PDF files. And it’s free! Thanks to Lifehacker for the pointer.
Windows only: PDF reader and Lifehacker favorite Foxit Reader has just released a new 2.0 version.
