Several years ago I listened to a similar opinion and it struck a chord with me. www is an outdated formality and I decided to purge it from my sites. I 301 redirected all www requests to the equivalent www-less version. I standardized the linking policy company-wide (globally) to link without the www when possible. I then standardized all business cards, brochures, pamphlets, catalogs and all other printed material to show the www-less version of the company URL.
