Having a scanner on hand that works reliably leads to occasionally scanning things. Got a form in the mail that needs to be signed and returned? Print it, sign it, scan it using Picasa, insert the image in a Google document, download it as a PDF, fax it using a free internet fax service, and off it goes. Not the most secure method of transmitting a document, but then what methods are really secure?
Today I got a five megabyte PDF from Detroit Steve that has a bunch of old photos he has scanned using his brand new scanner, a Fujitsu ScanSnap iX500. Compare to my HP Photosmart scanner it is blazingly fast. It will scan a couple of dozen photos in under a minute. Of course it costs more than a buck and a half so I will never buy one, but I do think it's a good idea to at least touch base with the current level of technology at least every once in a while, just in case something cool comes along.
