Dropbox and a NAS or file server fulfill different needs with not that much overlap. Sure you can probably hack your NAS to be a bit like Dropbox and perhaps you can hack Dropbox to work a bit like a NAS, but a the end of the day they're complements not competitors. If you don't need what Dropbox offers that's cool, but that's not the same as saying that Dropbox doesn't have anything to offer over a NAS. Personally I use both and would never want to trade one for the other.
