Jiffer, you crack me up 
I've moved from considering fixies an absurd concept to being kind of tempted. A very light bike with few moving parts (and less MAINTENANCE!) with a direct and strong response sounds fun. But I think I'd freak out at the spinning downhill thing. Singlespeed maybe, sometime.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
