If we could deploy Apple products in a business environment we would in a heartbeat. But Microsoft just is better here currently on a lot of fronts - the last time I chased my tail here it didn't pay off.
If Apple wants to compete for the business market I think they should! We need first class user account management that INTEGRATES with other stuff (ie, google email etc etc). Right now you can federate from active directory to almost anything (SonicWall/VPN for remote users, WiFi for onprem user devices, vSphere for VM management etc etc). If you sync to google you can then use google one click sign-ons everywhere on the web SAAS side.
We then need office running perfectly.
Then we'd probably do our legacy apps on some VMs and chrome for SAAS apps.
We also need to be able to run MacOS virtually. We have remote users who talk to an on-prem VMs, separates their personal and work stuff, we can lock down and monitor the on-prem VMs and they can watch netflix with no worries using home machine. How does this work with Apple? It's easy with Windows.
I think there would be some demand from smaller co's to make the switch if there was a solution which allowed what folks are looking for -> migration to cloud as offices go virtual with controlled "desktops" delivered to users while still allowing in office / warehouse / factory deployments.
