For many years I wanted a large keyboard with keys with Cherry switches so that I could feel and hear each click and enjoy the feedback from the keyboard. I got all of that in my Corsair keyboard and enjoyed it for a while.
The slim and compact size; The soft-touch quiet keys; The low profile keys (I am surprised that I like this feature); The wireless capability; The anticipated battery life
Add backlighting to the keyboard albeit that the long battery life may suffer a bit
