I'm very much in favor of using mod_pagespeed but so far I have not been able to convince others to make the leap. Maybe being out of beta will be the convincing factor.
There's a video at [googledevelopers.blogspot.com...] that shows side-by-side comparison of the same page loading with and without the module turned on. It's pretty convincing to me.
