First, I would like to give you some major props. Installing Arch, in itself, is a big deal. It is not a beginner-friendly distro. It is a very power-user friendly distro and has an incredible wiki that is helpful, at least to some degree, for many distros.
For a beginner distro, I would recommend Linux Mint for its easy transition and great focus on user experiences or Bazzite if you really want to install and get gaming.
When taking drivers in Linux, most are provided as either kernel modules (integrated into the kernel, so you don’t have to worry about installing anything) or packaged for the distro, in which case, once installed via package manager, they’ll auto-update whenever you update system packages. They are so much easier to deal with than Windows drivers (for the end user). For example, to use a Wacom drawing tablet, all one has to do is plug it in.
Absolutely. I’m just accustomed to seeing the currency sign on the left and prefix abbreviation on the right (ex. €300k). Generally, it gets “expanded” to thousand, million, etc. So, three-hundred thousand euro. The things that amused me is thinking of a kiloeuro as a measurement unit, rather than a currency unit.
