Try Linux in a virtual machine, live DVD, or on an old spare computer preferably. It's pretty good for meeting the majority of people's daily needs without tweaking, and for the special cases compatibility layers like Wine and it's derivative Proton have gotten really good at running a lot of Windows only software. Honestly, when I moved to Linux, I quickly realized that I didn't need a lot of Windows-specific software because Linux has quality open source alternatives for most software. I despise using proprietary software and prefer open source (especially GPL2 and GPL3 licensed), so I have no issues using Linux.
And you'd be surprised how many mainstream software programs are available for Linux now.
I've used Microsoft Teams, Slack, Skype, Zoom, Discord, TeamViewer, Dropbox and a hundred other office/business/productivity programs for Linux.
For the Internet there's Chrome, Firefox, Microsoft Edge, Opera, Thunderbird -- notice all the big names are there.
And I've not run across a use-case where LibreOffice isn't sufficient compared to the expensive Microsoft Office. GIMP does everything 99.99% of people want to do with Adobe Photoshop. Audacity is a great free sound file editor available for Windows and Linux. I do all my editing of movies/docuмentaries with KDENlive. I use it *all* the time to make PG versions of movies I want to share with my kids. Handbrake extracts DVDs into files; K3b or Brasero is what I use to burn DVD or Blu-ray DVD media. Inkscape is a great vector graphics program. Blender is for those into 3D modeling.
Things like zipping/unzipping files, printing to PDF, screen capture, video screen capture, video/audio/DVD playback, etc. are just part of the operating system. Any handy utility you can imagine either comes with Linux or is quickly installed. I have to bring this up because these are programs I literally used to install on every machine, after installing Windows XP. Now I don't have to. I install Linux, and these things are good to go.
For software development there's Android Studio, VS Code (by Microsoft), Arduino IDE, MySQL Workbench, Filezilla, Netbeans, GEANY (a great lightweight software dev's text editor) and hundreds of other IDEs, etc.
I can run virtual machines with VirtualBox, test apps on virtual Android phones and tablets (emulation works great), and every piece of hardware I've thrown at Linux works great. Pretty much anything you want to do with a computer you can do on Linux.
What's more rare, and easier to list, is what I *can't* get because I'm on Linux. There's a reason our household doesn't even own a Microsoft Windows PC. It's not because we're not heavy computer users -- I know there are some families that don't use computers much. As I said in another thread, we have 8 Linux PCs not counting the CathInfo server and tons of Android smartphones. We're a very technical household.
The *only* thing I will grant is that we're not a PC gaming household. If we're going to play a game once in a while, it's more likely to be a retro 16-bit Super Nintendo game or something. We don't play current, popular, online multiplayer games. Talk about an addiction and a time sink! Might as well get into Social Media or spend hours on the TV set.
But even for PC gaming, Steam supports Linux now. There are hundreds of games available for Linux on Steam. Suffice to say that
a lot more people could switch to Linux compared with those who HAVE done so, or REALIZE they could do so.
