Between Evernote, Office360 and Google Drive/Docs, etc. I'm of the opinion this was wasted time and money; and that it will not be a revenue or user growth driver for Dropbox. There are gaps in sharing and collaboration where paid demand exists. They include: end-to-end persistent encrypted sharing; File authentication; handwriting recognition/search; rule and ML based box culling; content-aware rules; mesh-network sharing; blockchain integration; content analysis for sourcing/data-viz; and so much more. I sense a lack of imagination at Dropbox.
