I'm optimistic because devices like smart phones and smart watches are things that benefit from having very low idle power when just displaying mostly static info but require a much faster refresh rate in active use. Being able to read them easily in bright daylight would also be a great plus. That's a good market.
Even laptops would probably benefit from it, when you're typing some text or reading a document you don't need 60fps refresh rate (especially if you can only refresh portions of the screen). That might save a significant amount of battery.
