I just got a Chromecast. While it is neat, and reasonably priced, the fact that it is limited to streaming on its own and only from certain apps doesn't really meet my needs. I'm looking for any feedback or personal experience with Miracast dongles that will mirror my Galaxy S4 to any TV I want. I'll be in a lot of places where the only data connection is that of my phone so the Chromecast will be completely useless.
