Agreed. Dropbox is one of those rare examples of a product that takes no explanation and just works perfectly all the time, every time. It doesn't do a lot, but those guys have their core product down to an art.

Whenever I demo something that I've built that seems mind-numbingly simple in the demo, I have to remind myself that things that work well should seem simple.

"That's it?" is a sign of success.
