Where are the portrait lenses?

Where are the portrait lenses?, article.
The article has some very good points related to reduced-frame camera and the lack of portrait lenses made for them.
So does the first comment on the article, where Brett says: "Or just go full-frame and be happy ;) I love the Canon 100 f/2 on full frame; fast, sharp, great bokeh, and cheap too!"

It is true, both Canon and Nikon have excellent offerings in the 85mm to 100mm area, and I have the above-mentioned lens, and it is just what is said. And if you buy a Canon 5D mark One today, you'll get a really good full frame camera at a good price I imagine, since the mark Two is out.
Of course all of that does not negate the silly lack of purpose-designed portrait lenses for the more popular reduced-frame cameras, Nikon D90/D60, Canon 50D/450D, etc. It should not be hard to make a good portrait lens for maybe $200.
