You basically take a picture of a document, and it saves it as a pdf file that you can upload to your cloud (dropbox, box, skydive, iCloud). Some are slightly better than others, but they are all pretty much the same. You click the share button, and then can send it wherever you want. I’ll see if Lens has any features that make it better.
Great, thanks! And by all means post back with your opinions and observations -- sounds like you're in a good position to review it.
