No F1-F12 keys? Maybe it is just a software I use all day (IntelliJ), but I think others also make some use of functional keys (for instance I like Windows convention that F2 is rename, whatever it means in a given context).
Same thing here. This isn't even a very extreme case, 40% keyboards also don't have a numrow. Still just as quick to type on if you're used to it, with less hand movement. Definitely not everyone's cup of tea, though.
I actually have the same frustration as GP. I usually want a 75% keyboard so that I can have my mouse close to it, and since I don't ever use the numpad, that works out great.
But I don't care about the keyboard being actually small, so I would absolutely love some of those "macro keys" like on the gaming keyboards and also direct access to media keys.
Yes, I know you can have layers and combinations, and it might not even be that much slower (or at all) with one of those compact keyboards, but I find it much more comfortable to be able to only push one key with one finger.
I sometimes use my keyboards while doing something else besides "full-on typing" with both hands on the keys. Granted, in those cases I wouldn't be bothered by a full-width keyboard, but having two keyboards is just not something I'd consider practical.
I configured it so pressing 1 and Q together¹ sends F1. I use this far more often than Fn+1, since I can do 1Q singlehanded/singlefingered.
¹ Actually 1 and ", because Dvorak.
