10.5.6 to 10.5.7 as a combo update 729mb even on standard broadband thats way heavy for an individual download ? multiply that up by the average number of users ? its a crazy waste of bandwidth, and i very much doubt all that update is patching its probably just wholesale replacement and cruft that might be needed. they need to work on trimming these updates down in size, and maybe fixing something more important like the poorly controllable search functionality in mac os x.
