There’s a lot more keyboards without the numpad and the block of middle keys - whatever they’re called - or with the middle keys reduced or squashed up awkwardly on the side, than full-size plain old 102- or 104-key layout keyboards.
I don't like reduced-size keys or reshaping the block of six keys. My guess is that reshaping the block of six keys (Insert, Home, etc) is to mirror laptop layouts, so one doesn't have to switch between different layouts mentally. No real need on a desktop, but on a laptop, space is often at a premium.
But getting rid of the numpad is something that I am definitely enthusiastic about.
There aren't that many uses for the numpad. In my experience:
-
You actually do a bunch of numeric entry. I think that very few people do this, but for those people, sure, it's useful.
-
A few games use it, largely because it happened to be there for numeric entry. Because laptops don't generally have a numpad, shifting to keybinding schemes that use it have become far less common.
However, the numpad sits right where the mouse would ideally be if the keyboard is reasonably centered.
In general, I'd rather have my hands stay on the home row. If you have to use keys off in neverland, like arrow keys or F-keys or the like, you need to relocate your hands. Preferable to use modifier keys and chord them with regular keys in the "main block" of keys. If you're a vi or emacs user, you likely don't use the arrow keys for cursor movement.
There was also a trend back around, oh, early 2000s to have a bunch of extra keys added to the keyboard, stuff like Play, Pause, etc. That seemed to kinda fall out of favor.
