Let's put it this way: if you are seated on the couch, your computer is linked to the TV, and you want to play a game that requires a keyboard and mouse rather than a gamepad, that is your option. In general, you can put it vertically while slouching with one leg tucked beneath you. Using a keyboard, it's simple to test any other Kama Sutra posture. However, if you continue to sit at the same table, the lining under your palms will be severely lacking, and the brush will get weary of the high keys.
