Nothing cloud. Regular software like Office, Adobe stuff, accounting software, industrial related software, and many more.

You use all of these?

Yes, I have Office (excel heavily), adobe (rush, photoshop, premiere, audition), QuickBooks and Sage 50, some automation software for manufacturing. There are many more that wouldn't work on anything but windows. I am sure many people are the same as me because I see other computer users with their software stack very often.

In that case you probably want a Mac. Its basically the same as ubuntu, but Apple paid the Microsoft taxes.

Mac is not enough although I have a MacBook Pro on my desk sitting and collecting dust. I only use it to test sites with Safari because emulators never give the same result.

I install ubuntu on old laptops to utilize them and as VM on my current windows machine.

Macbook is sluggish (mouse moves) and very limited customizations/options. None of the communication software I use work all at the same time on either on ubuntu nor macos. For example, I use Skype, RingCentral, WhatsApp, Teams, Discord open in one 32" monitor. I must communicate with multiple people everyday for business purposes. I can't fanboy and go for Mac or Ubuntu and ruin my businesses. (I have 4 x 32")

Another monitor has KeePass, putty, and winscp running. If a client sends me an excel file for a reason and it has macros in it, office is the only way to open it. OpenOffice or Libre sucks. I also occasionally update company blogs and must edit photos and videos. Adobe works flawlessly on Windows and has many advantages using it on Windows compared to MacOs edition.

For my security cameras, I use the camera system's only supported windows software. There is no other platform supported. SonicWall VPN sucks on mac and unsupported. I won't spend 2 hours each time VPN fails on Ubuntu. Windows works flawlessly and I tried on Ubuntu. Can't connect to client servers remotely with Ubuntu or crappy mac vpn software called MobileConnect.

I use FreeCad but tried AutoCad in the past, only works on Windows properly. FreeCad sucks on Ubuntu, AutoCad is not supported. This is for my another business unrelated to the other software.

I have more computers than I can count but I am always ending up using Windows for work. To make everything work on one computer, I must use windows. If something new comes up, I won't spend hours and days to try to make it work on Ubuntu or feel sad for not even having it for MacOs.

Office Mac is pretty awful, I really wouldn’t recommend it for anyone who needs to use the full feature set

Ive had the complete opposite experience.

Office on my M1 macbook air is noticeably more stable and responsive than the dell xps13 bought in January, and the mackbook was like half the price. That XPS is probably the last windows machine we buy ever.

Also most of our employees have fully migrated to libreoffice now.

The GP meant features. Office Mac is missing a great deal of them, like all the Power*/DAX functionality. And even if it has them, they might be half-baked; just to connect to pgsql, you need a paid odbc driver that costs about the half the price of the Office, you cannot use the open source one.

Oh dear lord

Have you tried CrossOver or Wine?

Yes, that's the kinda software that most office workers use. Programmers are the exception.

Any software developer business founder/entrepreneur uses more than Vim or notepad++. To support a bootstrapped business, the owners end up doing everything, this involves blogging, video editing, even photography if the product is physical. Just-one-software-using developers usually work for a company rather than being independent.

There are open source options that work fine on Linux for most of those though and things like Proton do a pretty amazing job now too. But people have set/complex workflows or existing familiarity that is not so easy to just flick over and that's reasonable.

It's not a "Linux can't do it" problem though.

Business founders/entrepreneurs are not exactly a large part of the userbase either...

It takes an unnecessary amount of time for to run things on linux that are working comfortably on windows without weird modifications to the operating system. That's the reason why people choose windows.

Regular software while doing "Business" !
