So Valve posted this press release:

Briefing Development Partners on New Features for 2011

February 28, 2011 - Valve, creator of best-selling game franchises (such as Half-Life, Portal, Left 4 Dead, and Counter-Strike) and leading technologies (such as Steam and Source), today disclosed its plans for a new "big picture" mode of Steam which will offer controller support and navigation designed for television interaction. Big picture mode will enable gamers to enjoy Steam and their library of Steam games on more screens throughout the house.
"Our partners and customers have asked us to make Steam available in more places. With the introduction of Steam on the Mac, and soon in Portal 2 on the PS3™, we've done just that," said Doug Lombardi, VP of marketing for Valve. "With big picture mode, gaming opportunities for Steam partners and customers become possible via PCs and Macs on any TV or computer display in the house."

Details regarding big picture mode are among the highlights Valve plans to share with developers and publishers in its partner meetings during GDC this week in San Francisco, Ca.

Well I guess that is one way to clean it...

I guess it depends on how it works. If they are talking about connecting a PC to a large screen TV, well that can be done already, if they are talking about providing software as a service where you play on your TV but the game is actually streamed from a remote stream and where ever you go you can log in and play, well that would be something I'd like to try. That would even work if I went to stay at a relatives house and wanted to play a game on their PC, instead of dl'ing and installing I could stream the game for instant play.

Valve can put whatever they want, wherever they want.

Cool dudes use mouse and keyboard on the couch, just saying. 

I'd be cool with Steam on the PS3.

Well Valve is bringing some steam functionality to PS3 via Portal 2. They have probably more in the works. Maybe more functionality for PS3s  (cloud saves)  , Bravia and Google TVs

OnLive does streaming, and if Steam did it and everybody praised it. I would /facepalm. "

They're just optimizing steam for use on TV's by adding gamepad controls and probably increasing font size & stuff, so people can easily use steam if they connect their PC to their TV. It's not going to be on the PS3, they clearly say in the press release that it's via PC's and Macs.

But what if Steam did it and it doesn't suck? Will you /facepalm then? "

So they will have an alternative interface for TV then?

Just changing text size (which is alright for me as it is on 1080p tv.) will do nothing. They will have to change the interaction experience with a whole new GUI for gamepads. Get rid of the tables and walls of text, menus and make it a more  touchy feely experience with more focus on images and objects instead of text.
