Seeing how courageously Dropbox moves into the territory of giants (first Cloudon, now Google Drive turf) the infamous Jobsian "you're a feature not a product" seems to be an iconic short-sighted mistake.
Really? Tell me how Dropbox is doing in 5 years from now after the cost for storage is infinite and free. Gmail already has google drive integration. Dropbox could've made this chrome plugin years ago. In the future all of Dropbox's revenue will most likely come from SMB's and a few enterprise customers.
Recently, it was reported that an MS me-too product was incapable of dealing with file paths of a certain length. In 2014!
I think this line "a feature not a product" is really really misguided (to avoid using a stronger word); a feature perfectly executed is precisely what a product should be.
So let's talk again in 5 years and see how Dropbox is doing, yes.
