I have two systems running Windows 11. I have been running Windows for about two years now, Windows 10 up until the release of 11. I had been a Linux user for around 16 years. Recently, I wanted to look at alternatives for older systems that do not qualify for Windows 11.
KDE Neon seemed like a good starting point because it is most similar to Windows as far as looking modern. Let's face it, many Linux distros seem to be stuck in the 90's as far as appearance is concerned. The majority of complaints about Windows 11 are because of the hardware requirements and very little ability to customize it.
Plasma Desktop 5.23 is KDE's 25th anniversary edition, on Neon you always have the latest KDE. The default menu is excellent! If you don't like it there are alternatives just a couple of moue clicks away.The desktop can be made to look just about any way you want, it is very customizable! It can run on old hardware quite well too.
Windows 10 is decent but eventually support will end. There are a lot of great older computers out there like the older Dell Precision's I have. I am not about to get rid of systems that have 128 GB of RAM, dual Xeon processors, etc because Microsoft decided they are not secure enough, they suit my needs just fine. Also, parts and new systems are very expensive!
I still want a modern looking system and Plasma 5 does look really nice! An avid gamer would not be happy running Linux, Windows is far superior for gaming. I game a little but Steam keeps getting better and there are a decent amount of titles available, so I can live with that. I can use snaps, flatpack's and app images to keep applications on the latest versions if I want.
I installed the flatpack for LibreOffice and it works great! I would not recommend KDE Neon for inexperienced users but Kubuntu will soon release a new LTS that would serve new users well. Most of Windows 11's new features have been in Linux distros for years, virtual desktops, rounded corners, compositing, etc.
Linux is not for everyone, if you are a hardcore gamer you would not be happy. If you just want a modern look, customization, and a future upgrade path, a KDE based distro might be worth looking at. I have no plans of switching all my systems to Linux but all my Precision systems are in pretty much brand new condition and I want to keep them in use.
Some had mentioned looking at Linux so I thought I would share my experience.
