One really nice thing about my Google Docs spreadsheet is that I can access the files from my phone, from anywhere. So although I do print a version, I really don't need to. I can pull it up and add comments, measurements, etc. while I'm brewing. I can also pull it up later if I'm having a beer with a buddy and they want to know details. Or if I'm at the brewshop and decide on a whim to grab supplies for a recipe, I have access to all of that through the magical cloud.
Google Drive is amazing. Everybody should just dump MS Officd and go with Google. I don't put my notes on Drive, but all of my recipes are there.
