Such a simple answer... all you goto do is visit a few major sites without the www. and see how many redirect you to the www.

http://google.co.uk/ -> http://www.google.co.uk/
http://youtube.com/ -> http://www.youtube.com/

but then again regardless of seo i will always remove www. for user simplicity and removing problems with subdomains etc when using a Subdomain as a CDN
