I know what you mean about the windshield pitting. The windshield on my dad's old 1990 Suburban has less pitting in it, and that's after 200,000 miles.
I guess driving too fast takes its toll on glass?
As for SEMA, it's nothing but a Bling Bling show, there are hardly any performance companies showing up with new products for late model cars, I think the giant 24" wheel craze has really put off the real performance enthusiasts and manufactures.
