Ask HN: Why do devs feel a MacBook Pro is required for development?

I'm curious why the trend over the past few years has resulted in engineers feeling like owning a MBP is a requirement? The vast majority of the tech startup scene seems to only tote around these machines and are very willing to defend their choice in hardware + OS. I often will hear the argument that it's impossible for them to be productive on anything other than Apple hardware running an Apple OS.

There are excellent text editors and IDEs available cross platform. Having a local dev environment that matches production is very easy due to VM software. Viewing the resulting product (most often a website) depends on the cross-platform browser, not a particular OS choice.

Would love to hear HN's stance and viewpoint on this peculiarity.
