This is really interesting. I've personally found the 120-135 degree angle the most comfortable.. I'd previously thought it was terrible for my back, perhaps not! I've actually been looking for a way to use a laptop or PC comfortably while lying on a couch. Does anyone have any recommendations for this kind of usage? An optical mouse is great because you don't need a flat surface. On-screen keyboard is also great if you really cant be f'ked. :P
