I have been an avid fan of PDF annotator for six years (I'm in science research). So I just wanted to email you and say THANK YOU! Thanks for creating such a great program and for making software that is so user friendly. As a consumer, I really appreciate it and you are definitely the exception in the field.

It's a killer-app on a TabletPC.

Alexei Gilchrist Brisbane, Australia

The real power and "Ah-ha" moment is when I pull up PDF Annotator in a video conference and my PDF becomes a virtual whiteboard. I write notes, edit drawings, solve problems, fill in blanks, in the group environment as if we are in a meeting room together. The whiteboard in the palm of my hand is my new most powerful application. I can live without most of the apps on my tablet if I have to. I can't live without PDF Annotator.
