GUI slows me down (Score 2, Interesting)

I'm a hardened Mac OS user, have been a graphic designer for the last ten years. I love Mac OS 8.6 and 9.2. Everything works just fine. OS X is definitely fast enough in terms of the applications working away, doing calculations - but the damned GUI is slow. And depressingly it's the animations, the sliding drawers, sheets - the icing which has been added - which really slows me down. Why can't us "professional" users have a simpler GUI which doesn't feature time-wasting animations?
