Dropbox Is Close To Finishing A Mega-Round That Could Value It At $5-$10 Billion

Unless they're literally building out a new data-center from scratch, or hire-aquring the competition (which you'd think would be anticompetitive) I can't see how they can spend that kind of money on anything worthwhile.

Dropbox is great, but there are a lot of very compelling competitors. That's not to say it's not going to be the best service, but it's by no way the only player in the game, and getting a round of this magnitude (if it's true) at this stage in the company's progression seems, for want of a better word, mental.
