I have three Apple IIe's (non Platinum) and on one of them, the open/close Apple keys are much larger than the other two. It's almost the size of the entire key. In fact, it almost looks comically large...lol
I can't say that I like it or hate it. I thought about swapping them out for my primary IIe and see if they would grow on me.
So when did Apple decide to shrink them?
