Man, I wish I had one of these before throwing out my huge collection of old
WHFB books:

I'm sure there are others on the market, but the features on this sound like exactly what would be needed to truly digitize a collection. I was thinking about this after taking pics of my Aeronautica book before letting a friend borrow it, and it would be really convenient to be able to have a PDF of all the books I have... without also paying for an additional PDF

(in a perfect world, there'd be a free pdf with every physical book purchase, but that doesn't seem likely to happen in the short term).
Anyway, just thought I'd share

. If you already use something like this (or the current version of this one) feel free to post your experience with it!
