There’s a lot of history behind the Phantom lapboard (and its ill-begotten console progenitor) but we don’t need to go into that. What you do need to know is that the Phantom lapboard is essentially a wireless keyboard on a hinge. You can (and must) lock it into an angled position to use the mouse on the surface below and to the side of the keyboard. Now, this raises a question: Do you like typing on a keyboard that’s locked at a significant angle to the natural plane of your hands? Of course you don’t.
