I have used Paperport for some time but stopped at version 10 which does not work with Vista. I expect 11 does but the last time I looked it was too pricey for me.
Personally I like PaperPort and found that it was a good way of keeping all my scanned documents filed away neatly. It has good folder utilities, and allows dragging and dropping into lots of programmes including email and fax as well as Word. The OCR worked well, not that I used it a great deal and I made little use of the photo side of PaperPort.
If it was cheap enough (£10 is about my limit) and it worked in Vista I would start using it again.
