Obviously not such a big deal for the Mac client, but has anyone tried Big Picture in Steam? I had a go on it on my PC (plugged into the telly) last night, it's superbly well designed, I just felt like sharing my enthusiasm! If it could be made seemless, eg launch fullscreen on startup so I never have to see Windows (maybe I can replace the Windows 7 boot images with Steam ones...) and not require switching to the Mouse to click the "Launch" button on games, it would be perfect.
