I would think the ideal use case would be for scientific equipment where a very precise temperature needs to be maintained. Right now you either have a large thermal mass to prevent fluctuations (which also means you can't quickly and precisely vary the temperature), or you just accept the thermal noise and try to compensate for it in the analysis.
