I've installed and used many flavors (distros) of Linux.
Linux can do almost everything that other OS'es can do, and some things you can only do in Linux.
Any of the basic activities you normally do on your windows or mac computer, you can do on Linux, such as web surfing, email, social media, forums, banking, youtube, etc etc etc.
And Linux tends to be very resistant to virus and malware attacks. This does NOT mean impervious...just that there are fewer attacks on Linux.
There are a few apps or programs that require Windows or Mac. But these tend to be specific pieces of software, and if you have paid lets say, $249 for Version 9.73 of XYZ-Super-Dooper CAD-SKYVIEW-STARMOVER Software Suite, (as an example) then that one will probably NOT run on your latest Linux Laptop.
Linux is ideal for loading on an older PC or laptop, maybe one that came with windows 7 or windows 10, and give it a few more years of life. Most of the modern Linux 'distros' have a free demo version, you can download it and burn it to a CD or thumbdrive, and then load it in what is called 'Live Mode' and try out the features, see if you like the way it looks, etc. If you do like it, you can install it from that CD or thumbdrive. If you dont like it, you just reboot the computer and poof, you're back to your original operating system.
There are a lot of good reasons to try Linux, especially if you kinda like fiddling around with the 'guts' of an operating system, tweaking it so it works exactly like you want it to.
If you don't know a 'file' from a 'folder', and you've never even heard of a 'command line'...then it will probably not be your cup of tea.
