> I wonder what features Dropbox can offer that won't inevitably be surpassed by Google Drive, iCloud Drive, and OneDrive.

It's strange but it seems like others aren't trying hard enough or simply aren't interested in making a great product. My experience with dropbox has been better than with any other cloud backup service. For instance, I can move my cloud folder around without forcing a re-sync of the entire data. I can manually copy data to a new computer & it'll be magically sync'd without re-downloading everything. Dropbox also does a great job of incremental updates on binaries.
