~iPad sales definitely won't be in strong year-over-year declines within five years~ - probably also Steve Jobs

Sometimes people build technologies that just aren't that attractive to people. I stretched a little for the Steve Jobs joke, but it turns out that sometimes you build something, it works, it's even pretty awesome, but a few years later it turns out that smartphones have 6" screens and tablets just seem less useful than they used to.

Or sometimes it's worse, and you build Google Wave to revolutionized and unify email, chat, and discussion boards and it turns out that people Just Don't Want your tech.
