Of course, there's still a massive market for Windows PCs among enterprise and power users, but as more and more enterprise software goes on the web, Windows becomes less of a requirement for businesses. The majority of business users could easily get by on a chromebook.
This is something that's frequently enough claimed, but it doesn't actually work out in practice.
The gotcha is that every enterprise has legacy software, and much of that legacy software is heavily tied to the desktop. It may be dependent on old VB versions, old Java versions, there's even still a lot of Lotus (spit) Notes (spit) out there.
Agreed, and tbf, I did qualify my assertions (see bolded parts). Right now, there is plenty of core LOB legacy stuff, but it is gradually changing and moving to the web.
And while I was probably overstating the case to say that the majority of business users could get by, I wasn't pulling that out of thin air.
To give a concrete example, my wife works in Human Resources and is changing jobs at the moment. In her old job, she had a Windows laptop, used Office, etc. In one of the new roles she applied for, they told her she'd get a chromebook.
The point is that it's an (admittedly slowly) shrinking market, and I say that as someone who makes their living from writing desktop software. Of the three biggest players in the tech industry, Apple have pretty much transitioned to mobile and Google never cared in the first place, but it's gotta be worrying Microsoft.
