Looked into it. Expensive and seems to be an attempt at Smart TV but walled into Sky with no useful apps. Okay has a fancy new EPG and does offline viewing on tablets (not Windows). It’s just other than looking nice it wasn’t offering me anything useful.
I’m looking at ditching Sky anyway as I don’t really watch the live TV content and little on the pay channels. Probably go with Freesat combined with my Amazon Prime sub, and my NAS full of downloaded stuff playing via the Plex app, as my TV is a Smart TV anyway. Though I might get Amazon Fire TV as it’s probably more reliable and has a better selection of apps.
