Adobe Acrobat: Searching For Alternatives

For a long time I have been frustrated by Adobe Acrobat and the never ending story of angst that comes with using it. Fortunately there are several very good alternatives to Acrobat out there, some of which are open source while others are freeware / shareware or paid. The moral of the story: if Adobe Acrobat is getting you down, find an alternative! You won’t look back.
