Yes, yes it is. I'd rather have them working on features that people will use.
People act like power consumption and value are important and then turn around and claim they will buy and power 3 monitors.
In reality it is a product looking for a market rather then a product responding to a market's needs.
Three monitors is better value for money than a $500 graphics card.
In fact, one of the few things that is worth spending a lot of money on is a nice display setup (whether that be 1 or 3).
I am incredibly happy with the £150 per monitor I spent 4.5 years ago getting some 17" LCDs, because while they are £90 now, I am still using the ones I bought said 4.5 years ago.
Other things I am still using: Case, Speakers, Mouse.
Things I am not using anymore: Graphics card (which was £210, more than one monitor).
Things I am now using in addition to said monitors: another monitor, 24" for my main display.
Buying 3 monitors isn't something everyone needs to do, but neither is buying a $500 graphics card. Buying 3 (or two extra) monitors is something which will likely last a lot longer than a new expensive graphics card if you are a reasonably high end user.
Also you don't need to have all the monitors on all the time if you don't desire. In fact, when I am watching a TV show/movie on my 24", I turn off the side monitors because otherwise they are just a bit of a distraction.
