I haven't read it yet, but plan to later tonight.

The man makes some sense -- but the F-22 is just too darned COOL to
eliminate.

I agree, that is my thought, also.
Sometimes you have to build a product just to advance the art. A
technology demonstrator just doesn't make the same convincing arguement.
The F-20 is a good example of that. It had a new engine and avionics in
an old airframe and didn't sell.
I also think the V-22 is great utility aircraft, but there have been
equally disparaging criticism written about it.
