1. At trade shows, the superior battery life and screen quality make our 1:1 demos stand out. It impresses a lot of PC-focused prospects. I can't go one day at a trade show without someone basically saying "ooh, wow, a Mac!"
2. Using a Mac with an iPhone means I can send/receive texts messages with customers/coworkers from both devices. Also, they like to see the blue bubble in Messages.
3. When used together with any Apple device, AirPods save a small but VALUABLE amount of time when a headset is desirable for meetings/calls. Seriously, AirPods are the least fiddly of any headset I've ever had to use with a computer.
4. Microphone, noise cancelling, and camera quality are quite good on Mac/iPhone. The experience has been better than any PC I've used and it's the general consensus at the company.
The benefits are so good that I would avoid working for another employer who didn't offer Mac as an option.
Also, screw Apple for their ridiculous prices, lawbreaking, gaslighting of their users, their stance on repairability, the lack of "Alt+Tab" in macOS, the lack of "Right-Click > New > Text Document" etc. in Finder, and other intentional choices made by Apple to limit functionality of their devices.
