Windows doesn’t work out of the box, you always have to mess with drivers, download your software from websites, and other workarounds to get basic tasks done.

Linux has most drivers included in the kernel, and most Hardware just works. You get a package manager which takes care of installing software and keeping everything up to date. Only for edge cases you have to download software from a website.

I suggest going with fedora, you’ll geht a recent kernel and a desktop of your choice with the different spins.

I recommend KDE plasma when coming from windows, since it offers a windows 10 style by default but can be customized to fit your personal workflow.

The repairable design definitely has some drawbacks, but i rather have a 90% machine that can be upgraded than a 100% machine i need to buy New every 5 years or so.

Soldered parts are often, if not always more efficient and the P14s (which I have at work) has soldered ram, which greatly improves efficiency
