The only issues I see are not being able to make the document searchable, but that is common with most free PDF creator software. As long as you have the full version of Adobe on your PC, you can make your PDFs searchable once you email the documents to yourself.
Make a PDF Anytime with CamScanner
I downloaded CamScanner about a month ago after it popped up on my list of apps in the android market. The app has become very handy on a weekly, if not daily, basis.
It allows me to take a picture of any document and turn the picture into a PDF document. Any time I come across an article in a magazine, I can turn those pages into PDFs and email them to myself so I can reference them later.
I recommend CamScanner for anyone who would like to reference documents, articles, etc. after reading them. It’s simple to use and very convenient.
