When Apple introduced iCloud I wrote an article about the potential impact in the corporate computing space: http://www.wanderingcio.com/2011/06/the-corporate-“icloud”/

In the article I compared what I was doing with Dropbox as sort of my corporate version of iCloud.  It turns out there was a LOT more there than meets the eye.  Dropbox may even have become iCloud had some things gone a bit differently.

Wired has done a great deep dive on this: http://www.wired.com/epicenter/2011/12/backdrop-dropbox  It’s a good read.
