I first purchased a Google Chromecast over a year ago. It’s been pretty amazing what this $35 has been able to. Aside from the obvious things like streaming YouTube, Netflix, etc there are some other really cool things like streaming security camera feeds. It’s a great shortcut for getting a lot of the functionality you’d get from Apple TV or Roku but at a fraction of the price (the Chromecast apps list now also includes Showtime Anytime, HBO GO, Watch EPSN and a variety of apps that will let you stream local media files, like MP3 or AVI files from your computer, phone or tablet).
I recently updated my home network (completely changing my wifi setup) at which point my Chromecast stopped working
