I think this needs a fix. The quantity box is also on the cart page.
Scenario:
No quantity box on the product page. User may still return to the product page and add that product again, or wish to add another on the cart page. If you have quantity turned off on the product page, quantity is still listed on the cart page, but not in an editable box. The rollover on the update cart button tells a user to highlight the quantity and change it. You can't.
I would suggest the option to turn off quantity box on the product page, and turn on quantity box on the cart page. Isolate these two.
Mike.
