Have you ever deleted an iPhone app you paid for? I have, albeit very begrudgingly. The app was Rise, an alarm clock that made waking up beautiful. I used it all the time, until they released an update that made it crash every time.

The buggy-release-causes-backlash-of-reviews-leads-to-better-release-to-fix-bugs scenario is pretty common. The point here is that these kinds of releases don’t have to be so common…thanks to phased rollouts.
