Yeah I really don't get it? Google is valuable because (the theory is) you buy advertising and you get more business and you make more money. So the more money you spend on google the more money you make. Ok I get it.

Facebook is valuable because it increases the (perceived) size of your social circle, and maybe you make more friends, maybe you get laid more. Ok I get it.

Dropbox you get synced files? Ok that's useful obviously but so what? It seems like at best a 100m business to me, not a 4b one, what's the angle here?

you must have never had a hard-drive that crashed, or a laptop that got stolen, or had to share a 2gig project with a friend.

2 things people pay for:

   - Convenience
   - Peace of Mind

I don't pay for dropbox but I'd just like to say that "peace of mind" is pretty valuable.

My friends use it to share pictures and music/movies. We don't have to think about it anymore. That's something.

Lastly, I'm a professional freaking software engineer and I don't know how to get files onto my droid x. Then I remembered dropbox has an app. Well what do you know; put file in folder; file appears on phone..! =)
