Here is a great app that I found that allows me to throw out my scanner and stay paperless. It is not for the big jobs but, when I want to scan a few pages at a time when I get papers in the mail, it gets the job done. I like how it uploads to my Dropbox which is a great way to keep my "filing cabinet" in the cloud.
Comment: WOW! I have just been taking photos with my iPad. Nice idea.
