I kinda was. I quickly calmed down, though when I realised Valve doesn't want it to be the default controls (like pads are on consoles), but more of a "good enough" replacement for mouse and keyboard in places where they aren't comfortable to use, like on the couch.
Frankly, this isn't for me - I'm nowhere a "comfy couch gamer" and I prefer actual mouse and keyboard in almost every game. However, as a tech thing it's pretty interesting. Especially how the touchpad with that haptic feedback thing will feel. We'll see how it's gonna end up.
