Google has lately adopted a new tactic to win mobile.
Over the past six months, Google has begun to systematically replace core, Apple-made iOS apps with Google-made iOS apps.
In July, Google launched Chrome for iPhone by replacing Safari.
In October, Google Search added a voice search as a new feature to compete with Siri.
In December, Google launched Google Maps to replace Apple Maps.
When Apple launched the iPhone App Store in 2008, it threatened to permanently disrupt Google’s most important business.
