I travel a moderate amount, and work while traveling. I've found I hate typing on laptop keyboards & touchpads after getting used to my home mechanical keyboard setup and decent mouse. Given this, I've started bringing my own keyboard and mouse with me when traveling, but the keyboard situation is terrible. I like having the numpad when I'm actually at my destination, but having it attached to the keyboard sucks for packing and tossing it into my backpack. Anyone know of a mechanical keyboard (cherry mx black or similar preferred) with a detachable numpad?
