I'm downloading and playing around with trial versions of a number of notebook programs out there, and now it's Devonthink's turn. I've downloaded the trial version and personally, I find this to be the best fit for my workflow and my future study flow as well. As I use this, though, there are some things I wonder, and I hope active users can give their insight. 1. According to Devon Technologies, they currently have a Mac-to-Mac sync process in public beta. Is anyone using that? Is anyone also using Dropbox to sync their databases by any chance? How good are either options? 2. Is the iPad version worth it? I would like to be able to check out the stuff I put together in the OS X version and read it on the go.
