I have Ubuntu 22.04 installed on my laptop for almost a year and it offers everything one can do on Microsoft or MAC and really cool thing is I don't have to install any anti virus here.
It's funny how people always argue Linux is a good replacement for Microsoft, but never the other way around

I am indeed pretty sure many Windows-users could switch to Linux, but not many Linux users could switch to Windows.
I am one who could not switch back to windows. The main reason I have already mentioned i.e. you can use Ubuntu for years without installing AV or any fear of getting infected with Viruses. There is a saying about Linux, "
Linux is also user friendly OS, its just picky about its friends"
While I agree with you about not being able to switch back to Windows, it should be noted that using Ubuntu out-of-the-box without a fear of being infected is not a sure-fire way to remain safe. There are still vulnerabilities that come with Linux, and recommendations to fix those. There are also great adjustments and tweaks that can be made to increase security.

You are totally right. The general assumption is that "Linux is unknown and therefore I will not know how to use it" however this is far from the case. Most distributions are entirely usable and their layout is quite similar to that of Windows. There are some distributions that are even designed just like Mac and Windows to make the transition easier. This is something I'd love to highlight if the board were to be added.
Even if you are new to Linux then there is so much online support available for Linux flavors like Ubuntu. You can find solution to any problem you are facing while using Linux. Plus Linux has been built in a way that it adds a security layer which is not present in other OS like Windows.
Agreed! There is plenty of online documentation as well. Most of the time, you won't even need to create an account anywhere or ask questions...a lot of questions that would come up are already documented far and wide around the web from others who have been using Linux. The greatest thing about Linux and its distributions is that a lot of answers for other distros can also help in the one you are using.
