Could Dropbox really have better engineers than the Google Drive team? Or could this be one of those examples of specialization - i.e. because the entire company at Dropbox is focused on just this one problem - so they are better at it, whereas the Google Drive team is just a small team within Google. As a result Dropbox has more resources at their disposal to make a better product? If that is the case, this could be the quintessential case study on why startups shouldn't fear large incumbents. Not only are large companies bureacratic, but more often than not they will have institutionalized inertia that prevents them from dedicating the resources to take you on - until it's too late.
