The 34" is a strange curved ultra wide beast. I'd rather a solid 4K.
For a while, Amazon IT wouldn't give us any macs besides 13" non retina pros. Managers started buying better machines out of their own budgets and using the "bring your own machine" policy. That shit ended quickly.
These days, Engineers seem to be on high end Macs or ultra books.
You also forgot to mention the EC2 instance size of your choosing provided your manager approved it which usually wasn't a problem unless it was something exotic since the Amazon internal rate for EC2 is very cheap.
IBM standard issue laptop is i5 cpu, 8gb ram, 256gb ssd - a ThinkPad T470 (Windows or Linux) or MacBook Pro 13". Developers get upgraded to i7 cpu, 32gb ram, 512gb ssd and have choice between lightweight ThinkPad T470P, heavy ThinkPad P50, or MacBook Pro 15" with only 16gb ram. The standard desktop is i5 cpu, 8gb ram, 500gb 7200 rpm, while developers get i7 cpu, 32gb ram, 1tb 7200 rpm - both on a ThinkCentre M910. I assume desktops get some kind of monitor (not documented), but laptop users don't get a monitor as standard equipment.
When hired, I was told I could have anything I wanted, but to keep in mind that the company is 95% mac. Got MBP 15" 16GB. Recently asked to get the battery replaced. They suggested I'd rather get a new laptop, to have state-of-the-art gear.
2-4 24" monitors. Hp workstation z440 w ssd & some large slower platter dives for storage, 32GB memory. A couple of laptops, user's choice, 16g memory minimum. I'm pretty sure it varies by group, however.
Lenovo ThinkPads, Apple MB Pro... Home office kit for VoIP phone, desktop video teleconference device, and wireless 891 router. Plus anything I need that my boss signs off on (ie. 88-core 768gb ram 8x800gb ssd server, switches, firewalls, routers, Meraki gear, and a dual 70" MX800) Expense small stuff like cables, adapters, and power strips.
