Wow, sounds like one heck of a wrestling watch, right?
Actually, I know I want a light-colored interior (bad experiences with black vinyl as a kid...). Early on some folks poo-pooed the beige as a dirt monster, but with the grey being pretty light, I wanted to see what real-world experiences have been with both colors. How do they show dirt, how do they resist stains, etc.
So if you have an EOS with either interior color, please post your experiences and observations.
