i wouldn’t generally say not ready for newbies. It depends on your hardware and your individual way of doing things.

you cannot just expect that year or decade long windows habits translate seamlessly to Linux. so there will be a bit of a wall to climb for most people and many failed attempts. that is ok. just try again if you feel like it and you will arrive eventually with a hell of a new computer related problem solving skillset you automatically pick up along the way

I switched a year or so ago and never looked back. there will be issues you need to overcome though. so better start with dualboot before windows 10 is eol

KDE plasma is one of the main reasons the linux desktop is so extremely good for me.

if you think so too, please consider donating to the project

kde connect is my recommendation also
