Looks great I already have the app on my iphone for steam that allows me to stream my games to the phone. Great if I want to just loaf in the bed and play my PC games but the drawback is the screen is a touch too small. This deck will allow you to travel and have a much bigger screen. Never got into the consoles to the gamepads much but this may change that.
Also, you can use the steambios or windows and do your own thing. Very cool.
I can see the attraction, but it's not for me. I like many of the things Valve and Steam do, but I've never been ford of hand held games. Especially on my phone.
I spend a good chunk of change building a monster PC, and that is what I prefer to game with.
