Sorry,
It was my mistake to say Justice Rheinquist opposed. He WAS with the Dessenting faction.
You can read everything here:
Opinion of the Court - Decision - Justice Stevens

Concurring Opinion - Justice Scalia
http://wid.ap.org/scotus/pdf/03-1454P.ZC.pdf
Minority Dessenting Opinion - Justice O'Connor
http://wid.ap.org/scotus/pdf/03-1454P.ZD.pdf
Separate Dessent - Justice Thomas

In the "Adult" business, you should pay close attention to the Dessent written by Justice O'Connor. She brings up a legitimate point of "what personal activity now is OUTSIDE the reach of Congress?" The answer, none, as of today. That includes you, your business and your computer, to say the least.
