Little devices that let your stream online videos from your phone, tablet, or laptop to your TV aren’t new. What the Chromecast from Google does offer, however, is a price tag significantly lower than most of the other options out there. For 35 bucks, just pick up a Chromecast, plug it into any HDTV, and connect it to your home WiFi network. Then you can stream video and music from your devices and watch some of the supported services like Netflix, YouTube, or Google Play. Simple, affordable, and, if you’ve never used something similar yet, life changing.
