Perhaps hunching over like a gargoyle is an exaggeration, but the very fact you need a flat surface to use a mouse/keyboard on precludes the fact that for 99% of PC setups you'll be sitting at least upright with your face close to the display.
Leaning back on your couch with a controller is indeed a different experience. Can't always do that either, which is why I like the choice of control styles the PC gives you.
