Haven't seen the show, but I think they are pushing all new stuff to please their sponsors. If everybody ripped out their old carpet and put in new hardwood floors that just puts $$$ in the advertiserment industry's pockets.. same with all the "new" stuff they're pushing..
It takes a brave soul to not fall victim to the latest and greatest fads in decorating... I bite my tongue when friends say they're "updating" their kitchen, etc..
