Without iMessage, right?

Most specialized software are web apps running in a browser hosted on the cloud these days. I’m sure they exist, but I couldn’t name any HR, ERM, CRM, … software that’s not a web app.

The desktop OS is becoming irrelevant. That’s why those who want a Mac or Linux notebook can make it work, at least from a purely technical point of view; i.e. if the company allows it. That’s also, why there will never be a year of the Linux desktop. (I mention Macs here, because while OS X gets some commercial software that you won’t get on Linux, it’s not that much outside of some niches)

There will never be a year of the Linux desktop because you gain very little from replacing Edge on Windows with Firefox on Linux (a different software that does the same thing). However, you loose some specialised software and your IT supplier, your IT service provider, half of your IT staff and some of your non-IT employees’ skills. This does not sound like a good business case.

Linux on the desktop never happened, because Linux on the server replaced desktop applications.
