Then they're not paying attention to how little of the pad they actually use, and the irritating-as-hell spurious presses that can cost you several minutes (or more) of work.
There's nothing like filling out a form (or comment) on a Web page to have it suddenly reload or back-page, deleting everything you entered.
I've literally never had a "spurious press" on a modern Apple trackpad.
I absolutely loathed non-Apple ones when I had to use them, the palm detection was completely useless and the cursor just swooshed around. I usually disabled the touchpad in the BIOS and just used the red nipple-mouse on Lenovos instead.
A larger and, more importantly, taller trackpad that also functions like a Wacom with Apple Pencil, which would compel Apple to adopt a more square display, 3:2 or 4:3, capable of showing more lines of code. Too bad that would cannibalize the iPad line, so Apple would never do it.
Many (including me) argue that Apple sells the best trackpads ever made, the size being a key attribute.
