John Gruber's *"Something Is Rotten in the State of Cupertino"* criticizes Apple's delay in launching personalized Siri features.He regrets not seeing signs earlier and outlines a hierarchy of feature readiness:

1. Vaporware: No demos or proof.
2. Company Demos: Only Apple shows it.
3. Supervised Hands-On: Limited media access.
4. Public Beta: Open testing.

Apple's Siri updates never progressed past vaporware, damaging credibility.Gruber compares it to past failures like MobileMe, calling for internal accountability to restore trust.
