I am looking for a word which is similar to nostalgic but with a different notion about the source of affinity. With nostalgia the affinity exists because of association with a prior “personally happy period or place”. Instead the word I am looking for shows an affinity due to a prior functionality.

Note: I would also be happy with an antonym for the word I am searching for. For instance when I take a crap in a toilet that won’t go down with a single flush and then attempt to wash my hands in an 0.4 GPM sink with water that only gets luke-warm and there is no towel to dry my hands I am not nostalgic for the old functionality but have contempt for the “new and improved”.
