Great thanks, guess they came with the Steam Box 300 beta kits, I got one for 29 on the bay today. (Now I have to google Chell) Ah Portal. I thought the same thing, perhaps he was in the Valve lobby and saw the display and kept it a secret from us all this time.
@Jackhead did you look how to do a factory reset? media.steampowered.com/steamlink/04_2015/dev/dev_builds.txt or 44 from media.steampowered.com/steamlink/SystemUpdate_full_44.zip might work? it would be a shame if you wiped an earlier build ofcourse. Maybe there is a way to get SSH anyway before trying these firmware. (normal retail steamlinks take their firmware from media.steampowered.com/steamlink/06_2015/. Random readers, its YOUR risk whatever you do with this info
