How easy is it?

var tel = navigator.mozTelephony;

// Place a call
tel.dial("123456789").then(function(call) {
  call.number;

  call.onconnected = function(e) {
    console.log('Your call to ' 
        + e.call.id + ' is connected.');
    // Play recorded message to customer
  }
});

How easy is it?

window.camera.takePicture('back').then(function(ev) {
  var blob = ev.blob;
  // Store blob in storage 
}

// WebRTC

navigator.geolocation.getCurrentPosition(
  function(position) {
  // position.coords.latitude
  // position.coords.longitude
});

var request = navigator.mozAlarms.add(
  new Date("June 21, 2015 16:20:00"));
navigator.mozSetMessageHandler("alarm", 
  function (mozAlarm) { alert("alarm fired"); });

Extra goodies

navigator.mozOs.exec('ls', [ '-al', '/data/local' ])
  .then(res => console.log('exec', res.exitCode, res.stdout, res.stderr))
  .catch(err => console.error('exec failed', err));
