I use a Lenovo X1 Yoga 2-in-1 for my daily and tried Ubuntu, Manjaro and PopOS. All of them sadly completely paled in comparison to Windows for out of the box tablet experience. Weird sizing issues, high battery usage, no face recognition login (extremely useful in tablet mode) I’m back to using WSL2.
* I've found scaling in Wayland based environments to be unbelievably good and sharp, but I'm also not using very user-friendly tablet-friendly desktop environments.
* High battery usage comes as a shock to me. I get better life on Linux, by far. Are you aware of the powertop tools & the tuning it can do? tlp? These tweaks buy me less than 20% more life, but that might change. Newer kernel versions are much better, and they also have far more aggressive defaults. If you were running an 18.04 Ubuntu that 4.15 kernel is not doing you any favors.
* No face recognition login is not something I'm interested in. It is nice to get back in the game fast, but worrying about 5s to throw in a password, to me, is small fries. And I don't really like or trust these systems in the first place.
But in general, what is notable about your post to me is that it's a weird laundry list of concerns that doesn't talk to the overarching experience. I've had detachable 2-in-1 computers for near to a decade, before that a Fujitsu P-series touchscreen+pen, all running Linux, but so far I've only ever used any of them in a more conventional computing mode. I have yet to break out Gnome or other mainstream multi-paradigm computing environments, but I am so interested to know, what is the workflow like, how would I use these things in tablet mode? As it is, if I want something portable, I reach for my Android phone. I'd like, some day to change that. These specific concerns you've listed seem low on my priority list, far below knowing & thinking about the overall general experience.
EV owner here. Why would I want to drive to a fueling station when I can fuel up at home with electricity? And from a maintenance level, ev’s have substantially fewer parts and almost zero maintenance, whereas hydrogen perpetuates the ICE-engine paradigm... frequent oil changes, many moving parts, lots of service costs at the dealership. The economics of H2 may be different at the commercial scale, but we use a Chevy Bolt in a far northern climate and get nearly 200 miles of range in the winter. The future is already here, and H2 missed the consumer vehicle bandwagon.
