Dropbox must have many more corp customers than evernote, no?
Maybe they are gearing up for a google merger or something. They are doing their mailbox app which looks cool and integrates storage and syncing. However, once again
1. Why would I use a mail client that only interfaces with gmail and outlook?
2. What is the point of the sync, this is default by most mail providers and clients?
3. Why would I want mail storage? I actually don't know what my mailbox limit is, but I certainly would not want to have the amount of .txt documents that could fill that up. Also, this is basic functionality. You can't pull me on your platform, google has the users you want and are better positioned, I still don't understand how you make money as a company.
