I consider PDF Annotator a “must-have” app if you work with PDFs and own a Tablet PC. That’s an arguable opinion of course, but take it for a 30-day test-drive and see what you think. If you already have tested the software but held off on a purchase, today is your lucky day. GottaBeMobile shares news that the software is reduced 51% in price today through BitsDuJour. That means you can snag a PDF Annotator 2 license for $34.95 today instead of the standard $69.95 price.This original version was packed with productivity, but version 2 adds even more functionality such as text search, a snapshot tool, and a bookmark manager.
