Galapagos

In my day to day life, the word Galápagos mostly comes up in reference to pre-iPhone cells that a person had to flip open (flip-phones), which are called ガラケイ(garakei), a compound of ガラパゴス (Galapagos, as in the Galápagos Islands) and ケータイ (keitai, or cell phones).  Generally, it seems like people use the term to denote old-fashioned, cheaper and less-than-cool phones, but this article from Forbes nicely explains some of the complexities implied.

Monthly bills for smart phones in Japan take a bit of a bite; I'm lucky if I pay less than 7000 yen per month, and I use my iPhone considerably less than most of my friends.  I like the article's parallel between Japan the island-nation and the island of Galápagos, even though it kind of scares me to think of things in such a way.  My favorite part of the article is its coining of the phrase "the spiderweb of death" to illustrate a cracked iPhone/smart phone screen.

Galápagos is also used in ガラパゴス化 (Garapagosu-ka, or the Galápagos syndrome) which, according to Wikipedia, "is a term of Japanese origin, which refers to an isolated development branch of a globally available product. . .a reference to similar phenomena Charles Darwin encountered in the Galápagos Islands, with its isolated flora and fauna, originally coined to refer to Japanese 3G mobile phones, which had developed a large number of specialized features and dominated Japan, but were unsuccessful abroad."  (see https://en.wikipedia.org/wiki/Gal%C3%A1pagos_syndrome)
