Acrobat Reader: Feel the love!
Rick Strahl posts I hate Adobe Acrobat (even more now!) and it appears, from the comments, that a lot of people agree with him. Adobe really has to do something about the Acrobat Reader. Personally, I don't have to worry about it as Preview displays PDFs on OS X without the need for additional software. When I was on Windows, however, I used Foxit Reader as it is much faster than Acrobat and doesn't contain any of the bloat.
