Regarding 3. Battery life - I’ve had a ThinkPad Nano for several years that, on Windows 11 would get roughly 4-6 hours battery, and this was optimized (very few running apps, no junk on startup, power saving settings on, etc). I switched it to Ubuntu (I was surprised that everything worked out of the box too, all of the hot keys and everything), and it will get about 8-10 hours doing the same tasks (primarily Chrome). So there is something to be said about Linux in general just being so much more “light weight” so to speak vs windows, which has become such a bloated mess. But the main issue I had was your point 4, since the thinkpads screen is 2K, everything was either too small (with no scaling) or too big (with scaling on).
