I'd love a Buttkicker, but Wife 1.0 is already installed.
LOL. Reminds me of when I was a the Honda dealer and the had one of those kickass Lazyboy chairs than vibrates and massages from head to toe for the customers to relax in while waiting for the bill, which after seeing makes you want to go back to the chair. I said to the service rep "what do you call this chair-the next wife?".
+1 for a toggle switch for the cockpit shake in VR.
