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.
So... we're talking about more than one blunder here.
