Of particular note, this also works on Android Chrome. So a site can send push notifications much like an app can. The Facebook mobile site uses it, so I&#x27;ve been able to remove the Facebook app entirely from my phone.<p>I really wish Apple would implement this as well, as it would remove the requirement for a number of apps that are just thinly wrapped webviews. Sadly, I don&#x27;t think Apple&#x27;s business model will allow it...
