Depend on which FAANG I guess. Approaching now 10y at Google and I saw Windows laptops only used by very few sales people. Everyone else is either using Macs or Chromebook.
Fellow Googler here. I'm the exception that proves the rule. After 7 years of Macbook and Linux devices, I needed Windows for a special project, so I got a "gWindows" device and found it very well supported.
Aside from the specific Windows-only software I needed, I would still just ssh into a Linux workstation, but gWindows can do basically everything my Mac can. I was pleasantly surprised.
