Well seeing how Dropbox is doing now, Steve Jobs was right - it isn’t a product, it’s a feature. For the same price of 2TB of storage on Dropbox you can get the same amount on Google or OneDrive with a full office suite.
People love to quote Dropbox ignoring all of the YC companies that are zombies or outright failed. Just looking at the ones that have gone public.
