Some windows-specific professional software that cannot run on Linux.
Also, work-related stuff. I may be able to make a custom setup of Linux if I try hard enough, but when it comes to dealing with servers and VPNs it’s a bit beyond me. Not to mention the time it takes to figure it out and set up.
Although, the more I hear about subscriptions from Microsoft the more I want to switch.
I think it works best in combination with fingerprint scanner.
Like when your fingers are wet and are difficult to scan. Whilst trying to make the scanner work, face unlock just does it for you.
But, yes, if it were one or the other, fingerprint scanner is simply way more convenient.
