"I just wanted to say this product is spectacular. It changes a tablet from a very cool, useful product to a must have device. In academia I read over one hundred PDF files a year and give all my presentations as projected PDF files. PDF Annotator completely changes the experience of reviewing papers and responding to audience comments in presentations. Great stuff. All prior solutions for marking PDF files were woefully inadequate."

"I have been very pleased with PDF Annotator. I thought it was a bit expensive at $50, but it has already paid for itself in saved color printer charges for 3 manuscripts that I have marked up and emailed to authors."
