Because those who make that choice believe (or have data proving it, but my feeling is that usually they just believe) that users are too dumb to understand.

That's a real problem in many situations: users are often under-estimated (they are also often dumb, which doesn't help).

They should invent a measurement unit for trackpads/touchpads, whatever we call them. Then a grade 5 touchpad will be immediately perceived as better than a grade 4 one. Or Basic, Business, Elite. Marketing teams are good at that.

> Apple doesn't put "better touchpad" on their labels either. It's just very very obvious that they're better.

Exactly. Everyone knows Apple has better touchpad, but nobody knows that about some random PC manufacturer. How will they signal that he has better touchpad in order to justify the higher price?
