That article, while enjoyable, is completely grandstanding with the title.
The final point - that 3D is readily available and no longer a major talking point is certainly the reality of the situation. It would be like advertising "HDTV" as the exciting feature. It just isn't exciting to buy a HDTV anymore. You are buying a TV? OF COURSE IT IS HD!!! You are buying a TV? About half the time (or more) it will be 3D... of course. So, it isn't exciting. It's not Tickle Me Elmo awesome. Instead, it is UHDTV or OLED (keep dreaming) or whatever else they come up with that is really cool and we may actually see in the next 5 years at an affordable price.
Yet, the newest products are ALL incorporating 3D from the start, and they are including the 3D decoding on the cheap chipsets these days. The new BenQ projector? Yep! 3D included for under $1,100. How awesome is that? A 120" movie theater in your home for just over a grand. Hey look, it does 3D as well. Yep, pretty nifty.
Nifty - not amazing, not awesome, not 'first to market'... Just nifty.
