One small add that I didn't notice before on skimming through - though apologies if the point has already been made - is that faster lenses give a brighter viewfinder image if you're using the viewfinder. This helps to see the subject in darker situations - and also allows AF to work through quite heavy ND filters in brighter situations. Also, as has been suggested, faster lenses are necessarily more expensive as (with a few Ltd exceptions) they tend to have more and larger glass - but as they already price themselves out of the consumer grade, they tend to be of better optical and mechanical quality. Of course what's fast depends in real world situations on the focal length - you wouldn't be able to lift a 600mm f/1.4 :D
