Evernote is a cool idea. They want to enable you to keep copy of all those random notes. In this example I drew a quick sketch on an index card (on this topic). I held it up to the little video camera on my Macbook and took this picture.
Then I dragged the resulting image into their application, and sychronized to their server. Less than a minute later I syncronized again and they had run a bit of hand writting recognition over my sketch. Not all, but some of the text was now searchable.
It works pretty well for business cards too. Fun.
