"Don't touch the pad on the side" ..... prototype or not, what kind of usability nightmare is that? You put on glasses by grabbing the sides.. The control should be based on your eye movements or something like a watch.

The kind that allows you to figure out what works and what doesn't.
I guess it has been almost 2 years now but I recall a certain phone maker giving the advice "don't hold it that way" when an actual product (in the store... being sold to millions) was experiencing an issue of that nature. I think they survived that. :)
