Some people might like them, some won't. [edit/clarification: someone rightfully pointed out that nobody will actively dislike a 4K monitor. I was unclear here: I meant "some people won't need them" more than "dislike them"] This sounds like when Jeff…

It will cost you less than $300 a year, which for any decent developer is less than 1/2 of 1% of your annual revenues (and its tax deductible for contractors!).
