The cable didn't seem to fit into the Ethernet port. Later found out that it's a kind of pull-out mechanism. Seems fragile to me, I would rather not have had it. The Fn and Ctrl keys are swapped compared to previous Thinkpads. Now it's the same as with other brands. If you're really going to work with colors, with video or photos, it's less suitable. It's also in the specifications. I only work with documents and watch instructional videos or follow live images of events etc. that's not a problem.
The only problem I haven't tackled yet is that a clipboard application usually doesn't want to 'paste', and that the browser sometimes doesn't want to load pages, can't find them, or the entire search doesn't work. I don't know if that's a problem in Windows 11, or in the settings. Other software I installed works just fine.
I also couldn't log out of the hosting provider, so it could be Windows 11.
