Affordances aren't arbitrary. The idea behind affordances is that the tool fits the user, not the other way around. If something is meant to be gripped in a person's hand, then it should be the right size and shape for a hand to grip it. Conversely, if something is the right size and shape to grip in a hand, that intuitively suggests that it is for gripping.

And you operate them using a mouse, which itself is a layer of indirection. So I don't buy the concept that affordances in software are not arbitrary - they don't refer to somewhat fundamental concepts for human (like grabbing), they refer to the last 100 or so years, when physical buttons became a common element of the environment one lives in. I see learning UI in computers as a process that begins with a new user having basic UI concepts explained to him, and then just following the changing trends, where a new trend usually makes "affordances" refer to the previous trend.
