Excerpt: Adobe Acrobat XI - Eleven Shades of Red Bureaucratic apparatus and Acrobat XI have two things in common, their appetite for paperwork and their fondness of color red. While Acrobat will never make red tape obsolete, it can add a nice bow to it and make the documents fly at speed of light. Vogons would approve.
Conclusion: It doesn't do everything, but Adobe Acrobat is still the most powerful, stable, and mature PDF application, from the creator of the PDF format.
Pros: Vastly improved editing features for text and graphics; improved graphical interface for combining documents into a single PDF; enhanced export capacity; improved online web-creation and document-signing features.
Cons: Massive feature set can make navigation confusing; a minor annoyance requires multiple steps when performing OCR on some PDFs.
