Hm, two things occur to me.
1. If you have the right sheetfed scanner like a Visioneer Strobe, you just take the document, slide it into a slot behind your keyboard, and it's scanned and filed in a general folder in 20 seconds. I guess it would be a P.I.T.A. to try to use some scanners with lots of software steps to get started on their (fairly slow) scan runs. Yep, I guess if I had to use one of these, I wouldn't be so keen on electronic filing, either. So having the right scanner that effectively becomes a transparent portal onto your desktop seems essential. Later anytime you can drag from the general folder to specific folders. The Fujitsu ScanSnap series of scanners look very good, although the Strobes from Visioneer with their Twain drivers are more versatile, and used to be the easiest to use.
2. Even if scanning takes a bit longer than throwing in a drawer, isn't it WORTH the time a) not to have to take up room in your study or office for a cabinet, b) not to have to hop up 40 times while doing your filing, and c) never having to make copies (just scroll them out of your printer)? Maybe I'm atypical because I was a lawyer for 25 years before switching over to tech, and the value of having my case and client files organized, at my finger tips, and SEARCHABLE was extreme. Even now, for instance, when doing tasks like filling out financial aid forms for my son's college, it is SO EASY to click a mouse and find ALL of our tax data (without getting up), ALL of his transcripts, resumes, and award letters, etc., that I can't imagine having to go looking for paper. And how do you search a filing cabinet? PaperPort 9.0 (the last one that was good) does OCR on all scanned docs and boy is it a boon to find things by word search as in Google.
It is a damned shame that PaperPort, which was a fine product (and still is if you buy Version 9 rather than the current Version 12, which frankly sucks) got Bowdlerized, savaged and vandalized by the current owners (Nuance? which acquired ScanSoft). The product has become a real POS but lucky you can still get Version 9. I wish Nuance would make this product good again (but they aren't capable) or take pity on Userland and spin it off to someone who knows what it can be. It could be an affordable and virtually-as-good Lucion alternative. What a crime that a truly great, superior, even classic program can be trashed by fools and turned into stinkware. Nuance, SHAME ON YOU. Personally I run Win98 in a virtual machine just to use version 9 with the Win98 Visioneer Strobe drivers that make life as easy as sliding all your stuff into the scanslot. Really.
I absolutely know this is going to be an area of huge opportunity. Whoever can wrest PaperPort out of the clutches of Nuance has the potential to become, if not another Adobe, then at least the owner of a product as widely used and useful as Acrobat.
