Nostalgia is the wrong term to try to connect with the millennials, if that is who they are going after. Nostalgia brings up memories of past experiences, millenials are too young by about 30 years to have such memories of this design language. However, I do think that they have an appreciation for such design language, to which I think they will understand the intent.
From my point of view, and has been said already, I think this appliance line offers a different/better option than is what is currently being put by the boatloads into new apartment complexes, and I think millenials will appreciate the difference.
