My current setup has 3 prongs.

My work laptop is a 2012 Macbook Pro. It's okay. I enjoy the MacOS UI, but
the particular year I have of the Macbook is plagued with some heating
issues while charging that, as far as I can tell, causes the processor to
NOP to inflate the amount of processor being used, making it a slog to
work with. Other than that, I enjoy using the Mac since I didn't have to
pay for it.

My desktop is running Windows 10, and is largely in existence to easily
game and stream(on the very, very rare occasion). I am not the biggest fan
of modern Windows(7 was the last great Windows). I also run some virtual
machines on there to do some dev work on other operating systems, as well
as run emulators for older computing systems that I am too poor to own
physically.

My personal laptop runs Arch Linux, and at the moment is very bare bones.
I have it running Arch with enough to get by to use for browsing, but I am
working on getting it into a dev environment state.
