I have two Apple Studio monitors and a max-ram MacBook Pro. Work only paid for the MBP and only after I jumped through the necessary hoops, which I was happy to do. Had they not, I would have just dropped the $6k myself. One time I did drop the $6k myself and then showed my manager. Show don’t tell. He expensed it for me.

A company would be foolish to buy everyone this gear. I buy it because it makes a difference for me , my eyes and my patience. When I was a kid, I had a 12” TV, not even a monitor. I’m not a kid anymore more. I think of it as a professional buys their own tools.
