Second,

my laptop (x201s) has a trackpad but it's so tiny that I don't use it.. in fact, I have it disabled entirely.

Clit mouse and USB mouse is good enough for all possible use-cases for me, personally. There is no increased value in a tiny trackpad.

However, my mac+trackpad is an absolute delight and I wouldn't be able to work without it. (on my mac).

So, if you're going to include a trackpad, make sure it's a exceedingly good one, and additionally, make sure it's used effectively by the operating system.
