Google is giving offices, particularly smaller companies and startups, a cheaper option to showing presentations. The Google Slides app now supports Chromecast and AirPlay, which means you can stream your presentations to a TV that has Apple TV or Chromecast attached to it. The Slides app also turns your device into a remote control so you can see your notes without it showing up on the TV and there are slide timers to help keep your presentation moving.
