I can understand the idea of 180 degree folding... screen is on the inside of the fold, it's protected, and the whole device packs smaller. You straighten it out, the whole screen is available. A 360 degree fold means you continue to fold the opposite way until the screen is on the outside of the fold. But at that point you can only see half of the screen at any one time, so it's less useful. You can't use this form factor for a laptop / convertible or anything that needs a keyboard anyway, so it's aimed at tablet / phone size devices, and for that size of device, losing half the screen size leaves you with a tiny screen, and you fold it to pack it away. I just don't see what advantage it could give over a similairly sized device with 180 degree hinge, and a secondary screen on one side of the 'back'
