I was referring to a standalone keyboard. You're right that there are some customizable keyboards out there (this one looks particularly good [1]), but unlike most people looking for a customizable keyboard, I'd like it to be both wireless and without mechanical keyswitches. I haven't seen those available. And for mechanical keyboards you tend not to have dedicated media keys (ideally, they'd feel differently so that you can hit them without looking or in the dark -- I'll never remember which order the volume keys, mute, and pause song buttons are in since it's non-standard).
