I use a big black cotton duck carradice saddlebag on my fixed commuting bike and it's superb. When I ride without it, I notice how much easier it is to accelerate, skid, spin the cranks etc but the convenience and comfort more than outweights that. I only have problems spinning the cranks at lights if I'm loaded up with files or groceries. I use a SQR quick release block on the seatpost so it takes about 1 or 2 seconds to take it off or put it on. And yes, I wheel the bike holding the saddle.
I always end up carrying more than I need to, but that means I can often find a vital spare part, an old malt loaf or some loose change kicking around in the bag in an emergency.
