Oh you mean how it was delayed numerous times and still came out to be a flaming pile of garbage? Yeah, that does not really work here.
The real problem here is delay vs the inevitability that the hardware will no longer exceed in its purpose or value in the constantly evolving market. If the delay takes too long, the hardware could reach close to obsolescence making it far less desirable than when it was first poised to release. (Anyone remember the Pandora?)
Delaying tech always has this issue, and the longer the delay the less it will be relevant compared to the technology that will continue to come out around the corner and blow this system out of the water. No one wants to be caught behind the curve (and pay 500+ dollars for it too) especially when its purpose is for gaming. PC gaming no less.
If I had taken the opportunity awhile ago to preorder a Deck I would have cancelled my order as well now. By the time it could come out its competitors in the market might actually have a better upper hand on the situation. This is not a good situation for Valve no matter how you look at it.
Also insert "Valve Time" Joke here.
