People just forget stuff. All this was said about Tiger. Snow Leopard was an entire paid OS upgrade the only selling point of which was that it made Leopard less crap. Your battery used to expand, your GPU used to overheat, you used to stare at a beachball helplessly every few seconds. You remember the good times, just like in ten years I'm going to remember fitting giant models in shared RAM on a monster GPU while the fans were completely silent, not this nitpicky stuff that has been par for the course for all operating systems forever.
