For starters, take a look around your home. Check out your home office, the entryway and the countertops. How great would it feel if all that paperwork were to vanish? There would be a reduced chance of misplacing important bills, and you wouldn't be scrambling to find stamps to mail late paperwork.
And can you imagine a world without a file cabinet or file box? In this picture, the file cabinet towers over the desk. A beautiful plant or just open space would be a more serene option to have if the paperwork in this home were online.
But as for the scanner it works perfectly - and the portability and size is great.
