But from where I'm standing, having never been a part of XBL, I can't wrap my mind around ever having to give away money to play online, or even download demos in some cases.
Voice messaging can be useful for sending in-game, childish, trash-talk messages to opponents in order to illicit the gamer-rage within us all (buddy of mine does this all the time ... quite funny). Or it can be used to keep in touch with long lost friends to chat with long distance for free.
Except it's not actually free.
As far as lag, both systems have their fair share, but as long as you're playing against/with people with decent connections, you should only be experiencing network problems on rare occasion (either system).
Seriously, it's 2009, and PSN is 90% of XBL for no charge at all. I'll take my Blu-ray, Bluetooth, web browsing, and third party 320GB HDD over cross-game invites, voice messages, and Netflix.
