Re Dropbox: AFAIK, most of the magic happens in the client. The way they seamlessly integrate with different OSes seemingly as an innocuous folder that blends in with rest of the other folders is genius.
I'm not sure what to think of this. On one hand this hack into the OS to improve the UX seems genius. On the other hand, what if the next version of the OS is not so easy to hack? Users will be upgrading to a new OS, but suddenly not able to use dropbox.
Also, doesn't hacking into the OS void the warranty?
