Yea it is user friendly. If you’re using your computer once a week presumably its for things like web browsing or working with documents - these are very easy and straight forward to do in linux.
The other big benefit is the cost - linux is free and you’ll save £120 on a basic version of Windows which can be used to get get a better PC or just saved.
Add to that no advertising, much more private and entirely yours to do what you like with. And if you don’t like it you can easily install Windows instead, so its zero risk to try Linux.
