I'm an engineer and I don't think like this, Bob. Instead I let to think so the marketing people in my company. Also the problem (in my eyes at least) here is that in terms of pixels there is only so much you can do with them. Few things come to mind - so if you have oh so many pixels you can:

* crop them as you see fit and still get a decent picture
* print really big enlargements
* if you do virtual 3D, your worlds will be more zoomable in, in a manner of speaking

That's about it. So the comparison with what Bill Gates said about PC RAM that someone here made looks invalid to me. PC RAM in particular and PC in general can do so much more so that adding RAM enables you to do great many various things. "Various" being the keyword here. As for pixels I am not so sure.

Although I know that you're a car enthusiast, Bob, I still think that cars can be a valid analogy. If you live in NYC or Chicago or Tel Aviv for that matter, do you really absolutely certainly need the likes of modern sports cars? Is acceleration from 0 to 60 MPH in 5 sec going to be a decisive factor for you vs the car that does so in 10 sec. In theory it may serve you well if you need to accelerate to escape a predicament on the road (*). But in the big city such a situation is possibly improbable anyway. The smaller, more frugal or less polluting engine is an entirely different story, and even more so in the big cities...

So MP count has to serve a purpose. And although in certain cases it does serve a purpose, it is unlikely to serve such a purpose for everyone uniformly. Hence I believe that there has to be "enough" pixels for 99% of the people out there, and 24 MP on APS-C sensor is just too many of them, little pesky pixels...

(*) It may be argued that if you get into such a situation or get close to it every now and then, you better not to drive at all or drive a slow car so as to force you to less aggressive driving.
