So the things Google Drive has that Dropbox doesn't: * 2-factor authentication! * Comments on files (unclear if it's only for Google Docs or all files) * OCR - like Evernote, you can search against text in images (e.g. newspaper article) * Image recognition - if you upload a pic of the Eiffel Tower, you can find it with the search term "eiffel tower" * Web-based file viewer - 30 file types including HD video, Illustrator, Photoshop, etc. The OCR and image recognition are going to be killer features for "normal" people. And I imagine it's something Dropbox can't easily duplicate (unlike the other features). Then again, as a more privacy-minded technical person, the image recognition feature scares the beejezus out of me. Tagging faces on Facebook is one thing, but being able to semantically identify all contents of my images is really stepping up the creepiness quotient. Should be interesting to see how Dropbox responds.
