What happens when your fingernail goes into the wood? Mahogany and Rosewood are both hard enough that these remotes will never show any wear unless you abuse them on concrete.
That also just reminded me of another big downside to wood: all the dogs I've ever owned have been really interested in chewing on wooden objects left around the house, even if they were otherwise perfectly respectful of everything else. I've lost quite a few shoe-polish brushes over the years.
