I agree, 'room temp' isn't exactly precise. Even if it could work at 'room temp' if it didn't work just above that it would be too finicky for a lot of applications. Somewhere around there is likely the 'magic' point for a huge number of applications that will change the world. The perfect would be, of course, one with a very broad range of environments it could perform in. I think we are on track to figure out how to make something truly sci-fi in its properties: Strong, wide range of temp/conditions, flexible, etc etc. Once we get the theory perfect I bet the world will really open up.
