Yeah I did think about it, which boiled down to "NVIDIA has working up-to-date Linux drivers" -- AMD used to be way worse and also there also has been a shortage of AMD-based workstation-class laptops on the market.

What I haven't considered is whether NVIDIA's Linux drivers might be implementing a particular graphics stack interface differently so that implementing Wayland on top of it becomes a PITA for some developers (not that GNOME and KDE didn't compromise to implement it anyways for users' sake). That does not make me a "shitty consumer", there is no way even a cautious consumer can take things like "GBM vs EGLStreams" fully into account every time.
