Will probably only mean anything to about 1% of ESR but the Twitch app on Xbox One has had a good update recently. Now allowing you to watch archived videos and also source quality with 60fps.

I did use the app a bit but the quality only went to high (if that) before and once you make it fullscreen is wasn't that great on a big TV. But now I can watch Zlive streams etc in best quality with 60fps sat in the living room on my 40" TV.

Good update... although granted, should of been there since the start.
