Is there a word describing a functionally obsolete design choice?

Question

I'm looking for a word that would describe something like a modern phone that retains a rotary dial. The dial's design was originally functional, but phone's function doesn't rely on the dial any more - it's just an aesthetic choice.

Answer 1

Yes. Skeuomorph.

skeuomorph /ˈskjuːəmɔrf/ n. a derivative object that retains ornamental design cues from structures that were necessary in the original.
