- Compose key blows your "ABC - Extended layout out of the water." It's more powerful than anything else.
- ... I never really use my XPS 13 without a charger, because I don't really travel around much, but it also has USB-C like all the "cool stuff." I would imagine with some tweaking I can get better battery life but I know it does last a while on standby.
- You won't get mainstream-mainstream stuff on Linux, which is probably a problem for some, but for day-to-day usage many Adobe alternatives exist (Blender, Inkscape, Krita, GIMP), along with commercial and professional things (DAWs (eg. Renoise, Reaper, whatever), and DaVinci Resolve)
- /shrugs VNC maybe? Although there are some pretty small monitors out there that should work. (I use HDMI monitors). Advantages of not being in the Apple ecosystem is that there is more freedom.
- Use a keyboard and mouse. It's faster. And more useful. There are only so many things you can do with a trackpad.
- You don't need to do much customization on Linux either (especially something like Pop!_OS or Ubuntu). Things are a lot better (not perfect, but better) than they were before. Nothing like Windows where you have to uninstall the bloatware though
