I found alot of issues with the Chromecast version of Netflix and the Chromecast device that I did not like. Some examples are:
1. No ability to pause, or fast-forward while streaming a move from my iPad.
2. I could shut down my iPad and the Netflix "cast" would still be running on the Chromecast device and my TV
3. It seemed like I had "no control" over the movie whatsoever once the content started streaming to my TV.
Now my oldest son who has a Droid device said he could do all that and more from his Nexus 7. I'm going to try my Nexus 7 tonight. I did read that Google did not implement many features on the iOS platform that they did on Droid devices, but then why would they? iOS is a competitor....
Laptops work well. You can have chromecast. ROKU3 is a great choice, for WIFI or Wired. Wired is really fast, movies come up in two seconds.
