I struggled to understand the relevance of Dropbox as soon as the alternatives of Google Drive and OneDrive came on the market with vastly more storage capacity. Is there a sizable market for people who require locally-stored content synchronised to the cloud (e.g. video editors?) Beyond that, the only people I encounter day-to-day who mention Dropbox are those not sufficiently tech-savvy to have known about the free alternatives mentioned above, and are still coasting on Dropbox's first mover awareness advantage.
