Hello Linuxkumpel,
Welcome to the forum
I have been using Linux Lite for about 4.5 years, it is the first Linux I used, but I am free of Windows for just about 1-1.5 years, so soon hope to be moving from newbie to beginner.
This my main desktop has Linux Lite as its OS.
The backup desktop is also Linux Lite as its OS, the backup is 32Bit and so is being retired/replaced soon.
I also now use a netbook I got at Christmas, this is Fedora Workstation, so I can follow a book that uses this.
