Somewhat relatedly, I hate hate hate clickpads. They are so much slower, unintuitive, and finicky yet every single laptop these days has the useless damn things.
I used to be so efficient with touchpads with tactile left and right mouse buttons. Now my modern laptop is practically useless to me without an external mouse, which significantly reduces its flexibility. I have spent days fiddling with utilities in Linux to alter settings to a state where its barely tolerable if I absolutely must use it.
