For me, OLEDs fall into a category exemplified by Anton Gudim's "YES, BUT" comic series.

YES, OLEDs consume less power, offer truer color reproduction, and are physically more compact.

BUT, they are prone to CRT-like burn-in.

SSDs, the same thing.

YES, SSDs are much faster and immune to mechanical failure.

BUT, they tend not to last as long as HDDs due to limited write cycles, and their price per GiB is still much higher.
