Yep, I’d never go back to a PC over a dedicated streaming device; I don’t recommend this approach if you have the choice! Just so clunky compared to the alternatives.
I’m happy enough with our Chromecast with Google TV units, and if I was buying now I’d look at the Google TV Streamer or - if I was to follow through on an intent to move away from Google devices - an Apple TV (though not sure how well 3rd-party apps support AirPlay from Android phones these days?).
