I read sites that are for system administrators (I don't know why, I'm a coder) and the majority of their posts are Windows, Azure or other Microsoft technology specific.<p>I know IBM has Linux, or did 10-15 years ago, across the org, around maybe 30% used Linux on the desktop even in Marketing. I don't know if it's still the case there.<p>It makes me wonder if there are any fully, just Linux corporations, no Windows.
<i>It makes me wonder if there are any fully, just Linux corporations, no Windows.</i><p>I don't know if this is still the case but Redhat had strict rules requiring all servers and desktops to be RHEL. By strict I mean they boasted <i>in front of my coworker and other customers there for the RHCE and their own employees</i> that anyone deviating would be fired on the spot. But this a long time ago <i>RHEL3 timeline</i>.
In web dev shops it's typically Mac for the workstations and Linux servers (in the cloud or bare metal). Maybe the accountant uses Windows and some devs use Linux but generally nobody uses Microsoft for hosting anymore (in this field).<p>Plenty of sys admins jobs there, they're just called something slightly different (devops? Cloud engineer? Etc.)
Plenty of companies using Macbooks as their primary machines. Though as soon as the finance/accounting departments grow beyond tiny they frequently get exemptions to be able to get Excel on Windows - all other options are sub-par.
