They have been 'coming soon' since May.
If I have a keyboard/track(pad|point) combo, I don't need/want a touchscreen. Thus I'd prefer a halfway-decent ARM chromebook over, say, a Transformer Prime, or an iPad+bt-keyboard-case (otherwise you're spending half your time with your arm raised, messing with the touchscreen)
It's not worth it.Just buy an AMD fusion laptop. I got the Thinkpad E325 and it's much more powerful than either Atom or all current ARM chips and battery lasts for 7h+.
