To remove ALL paper media from my house, what portable scanner scans the fastest? I want to carry that scanner in a backpack / gym-bag so I can scan my papers even when on the go. I hope for my house to become THE most paperless home in my town!

I want everything of mine digitized, that was originally in paper form. Also, I want my life to be easier and feel less cluttered. I can handle digital clutter much better than the physical kind.

So if there's a scanner I can take with me all the time, that scans the fastest of them all, that'd be great.

The reason why I'd want a portable scanner and not just an ordinary one is because if I'm taking mass-transit and it's a long ride, it helps to have something to do (like scanning and recycling my papers). 

Same for when I have to wait at a DMV, sit through a boring sermon at church (while away from most others to minimize the distraction) and anything where I'd feel inclined to get imaginative just to pass the time.
