Linux works well on supported ARM platforms, but the problem is that a lot of ARM platforms aren't supported. I recently got a Xiaomi Pad 5 Pro (had to import it as it's a China-only model) and put postmarketOS on it. The experience is surprisingly good. Paired with a Bluetooth keyboard/touchpad, it is basically as functional as a normal light-duty Linux laptop except for the lack of x86 support, which mostly just means no gaming. I have been attempting to run Steam via box64 and FEX, but pmOS isn't a supported distro for that so I have been trying in a Docker container and in Distrobox. I managed to get it started but it crashes due to steamwebhelper, and I think it's a dependency or configuration issue. Otherwise, for browsing, coding, videos, terminal use, office, etc. it's great and the battery life is amazing compared to my laptop. This is on a Snapdragon 870. Open source games run and they can hit 120fps on the 120Hz screen. I hope to see ARM support continue to improve, but I am worried about bootloader locks on these new ARM Windows machines.
