It doesn't quack, but the no-frills HyperX Ducky is easy to use and with all the RGB bells and whistles we've come to expect from a mechanical keyboard for gamers.

I don't understand the usage of the very small keyboards. I like TKL, but not this.
For games there aren't enough keys.
For developers - most IDEs require to press the functions keys.So, for a 3 keys shortcut you need to press 4 keys on this keyboard .
I think some people like these keyboards for: aesthetics, enjoying the challenge of learning to type on fewer keys, and the exclusivity / inclusion of being part of a small-keyboard-enthusiast community.
Also not every programmer uses function-keys often (I don't).
Gamers can re-map keys to play fine.
Plenty of computer users may be neither gamers nor programmers.
Macbooks have already trained hipsters to expect less and less keys; this is just a natural continuation of that trend!
