A very conveniant way of simplifying big shapefiles is dumping them in PostGis/Postgresql using shape2pgsql, then creating a new geometry column and fill the data with "UPDATE <table> SET <newcolumn> = simplify(the_geom,0.01) where the 0.01 is the tolerance factor, this number works well for me in longlat units. Then you can dump the table back to a shapefile using pgsql2shp. This way, simplifying huge shapefiles is really fast and stable, while in ArcGIS it's taking hours, and then just crashes.
