It's missing essential keys or hides them unnecessarily behind modifiers. Some keys are in odd places (FN). On the other hand there are two space keys without good reason.
But the worst thing: it's a wired keyboard. Which means it's being used on a desk, which means there's enough space to have all keys.
It's just stupid. Some people like stuff others deem stupid and that's completely okay. I don't have to buy it, I don't have to like it. But omg is this a stupid, stupid keyboard. For the sake of stupidity.
FN is rarely used I have the function and media keys on that layer. It's deliberately there bc of the little use I make of it.
All my modifiers are at my thumbs, holding left space bar jumps to nav layer for hjkl as arrows and some other nav keys, holding right space jumps to my symbol/number layer.
It's not about real estate, if I would be devils advocate here, why have a shift key or why have ctrl key if you could have capital letters as separate keys? Or all of your symbols in extra keys to your numbers? It's all about low travel with your fingers, I rarely mistype bc I dont have to aim for a key that's far away, and I can customize the layout however I need it.
I'd encourage you to try some leaner layouts for a while, maybe you find out it's not stupid after all.
Thank you for explaining me how these weird keyboards are used. Very interesting even if I'm too old and not clever enough to even feel the necessity to try it.
