Not just an Air Force problem.
At every agency I've worked at, people were given sub-par machines. The joke was, "We bill by the hour, don't we?"
McCann, AKQA, Digitas... was always standard to give people 5+ year-old laptops, often without even wiping them between staff members. We had one new hire, a junior UX designer, try and screen share with a client only to realize all of the bookmarks were packed with porn sites.
I remember in 2018 getting an 11" MacBook Air with 2 GB of RAM on it... as the team lead for a $25M project. Just a total joke. It was on par with what the devs were given. "Be happy they gave you a Mac!"
Meanwhile, 50% of the CPU was taken up with some BS security scanning program IT installed that require you be on the company VPN, and junky VPN software that hadn't been updated in 5+ years and only supported like 15 people trying to use it across the whole company... and it seldom worked from clients' offices... the moment I got on-site, my laptop was nothing more than a paperweight. And even if I could log in, all my bandwidth and CPU would be spent trying to backup the computer.
And... when I fought for better machines for my staff, at AKQA I was told by the MD, "Just drop it, we aren't going to spend any more money on hardware. You're being obnoxious and there's no benefit." Meanwhile my team was bringing their own external keyboards, mice, and monitors (and dongles) because the company wouldn't supply them. Ever try and design for 4k screens on a 11" MacBook Air with 2 GB of RAM? Ha. Most everyone just resorted to bringing personal equipment when they had to go on-site. It was too painful to use the company-issued junk.
It's a lack of understanding. Some bean counter who only uses his computer for checking Facebook all day assumes that nobody else does anything else, so 2 GB of RAM seems like enough. Meanwhile, the IT guys -- who aren't ever client facing and seldom needed the powerful machines -- all got top of the line equipment. "They're IT, they need it..." Um... wait what? At a time when I couldn't get my designers even 1 4k monitor, the IT guys were all rocking dual Apple Cinema Displays. Yay agencies!
Anyway look, it's all maddening. Make sure it's easy for anyone to put in for the tools they need to do the job well. Give everyone a new computer ever 3 years, keep staff happy and productive. Give the old ones to charity, get a tax write-off. Seems like that would work fine.
