I don't agree. I use a full size wired Apple keyboard now and use the PageUp/PageDown buttons. I prefer it that way. Also Home/End scroll to the top and bottom of the entire document vs the beginning and end of a line and I've had to fix that in software settings.

That said, everyone has their preferences. I think someone else in the comments mentioned how it would be nice to have a fully 100% customizable keyboard. I agree with that idea.
