It will never be the year of Linux. That statement doesn't even mean anything. Businesses desktops run on Windows. Linux wont replace the ease in which MS allows you to manage thousands of people in the near future. There will be billions of Windows computers for the forseeable future because they can be managed easily by sysadmins with AD/M365.

Out of curiosity, have you had any experience managing 100s or 1000s of users/workstations?
