I know the user for a touchscreen laptop, it's my wife, who had an HP Envy with touch screen running Windows 10 and found that on particularly unwell days, clicking by touch was just fine.
her current is a non-touch HP Elitebook (also Win10) and I asked and she would quite like a touchscreen laptop again. hardest part would be finding one that does Win10 and doesn't require Win11 if you have specific cause to run Windows.
so don't say there's no use case for a touchscreen laptop. instead, say the current ones are shit.
EDIT: linux advocates who are about to essay "why don't you just" should just fuck off right now
@davidgerard the Surface 3 Pro worked pretty good (the 4 had all sorts of weird build quality issues). My old Dell XPS laptop is still very functional.
Are the new crop of Windows 11 devices not allowing Windows 10 installs?
