I brought a Doxie Go last week and you are right, its a great bit of kit, I love it. Wish I had bought one a while ago. I can highly recommend one of these if you want to digitilise your paperwork. The supplied software is also all you need. Im using it on a Mac and have absolutely no issues at all.
If you are considering one of these, just buy it, you wont regret it. 🙂
