It annoys me when people label the PS3 as a media center and not a gaming console, when the PS3 plays games much better then the 360 AND does everything you'd expect from a home entertainment system.
It's also annoying as forget when the systems online play is bashed for reasons that shouldn't justify a purchase of the 360.
Yes, there are fewer people using mics on PSN, I have never found this to be a problem because usually the more mature players, who are atleast 15+ have a mic. Imo it makes the experience more enjoyable.
No, XBL is no faster then PSN. In my experience it's actually been slower.
Ontop of that from my experience the 360 is more of a childs system, or a system which you need absolutely no taste in games to play. Brimming with stuffty shooters and 1337 uber l33ts on Halo and MW2. Annoying as forget.
When it really comes down to it when you buy a system you're going to want to look at the games, in this case contrary to popular belief, 360 has no games. Some of you might haul some exclusives statistics out of your ass, but in the end how many of those 360 exclusives don't suck massive horse rooster, and how many of them do you play on a regular basis?
