$35 for a light switch? Ouch. I wouldn't pay that much for a light switch if it let me think it on and off with my mind.
I have to agree. I think this stuff will be obsolete in 5 years anyway, when gesture control of the light itself becomes more standard. No more need for these switches on the wall separate from the light itself. I'm saving my money. These new switches only offer negligibly higher functionality for a huge premium.
Never buy anything ending in .99 ... unless on slickdeals.
