I think Dropbox is valuable enough to become ubiquitous but one imagines they need to grow to a certain size before such a feature exactly is rolled into a version of one of the big operating systems. Not that what they've done isn't technically difficult of course, but it just seems like something so valuable it might be on a Chrome wishlist.

Cool thing if the guys who make the software are reading this - started a new job earlier this year at a mostly non-software company managing a few development projects. I doubt most of my colleagues are aware of this startup culture or have heard of .NET much less Y Combinator.

First week "You've got to see this program we have the sales team using, called Dropbox... its tremendous there's about a thousand things we can use it for". Not only are they using it its their "we're showing this off to the new guy" thing.
