This thread is full of wrong fanboy facts now that haven't got a clue what they're talking about.
How about instead of trolling you actually post useful information that supports your position. Otherwise you have contributed absolutely nothing to the topic.
On topic there are tons of inaccuracies in this thread, especially coming from the people who blindly support the PS3. Other things are small inaccuracies that are just misinformation probably heard from someone who has no real knowledge of the information said.
It breaks down like this:
Graphics: Most of the PS3 supporters in this thread say the PS3 has "better graphics". There are some instances where this is true, but the bulk of games that are multiplatform have better graphics on the 360. This is not an opinion, this is fact.
Along these lines both the PS3 and 360 support every (480i to 1080p) HD resolution and both have HDMI support.
Online: Xbox Live is $50 a year and PS3 Network is free. You get what you pay for. Xbox Live is significantly better in every way possible.
Media: Playstation 3 has a Blu-Ray drive. That's a huge plus for movie fans, but in terms of gaming it has yet to be utilized. Most games don't even fill up a DVD disc let alone a 25 or 50 gig disc. The only instance of a 25 gig being filled was from Heavenly Sword, a six hour game. So it's possible to fill up a whole disc with out compressing the audio of 10 different languages. Other than that it's not even being utilized.
Along those lines is the online media content. Xbox 360 has literally thousands of movies and tv shows, most in HD available for purchase on Xbox Live. PS3 has yet to even match 360's marketplace.
Red Ring of Death: This one is a funny one because every new 360 on the store shelves have this problem resolved. Not only that but Microsoft fixes the consoles for no charge if they do get the RRoD. They took a billion dollar hit to make give consumers a free repair.
Controllers: Saying one is better than the other one is just an opinion. It all really up to the individual.
I personally find the 360 to be the better controller for the games I like, but the PS3 controller is nice for certain types of games, mainly fighters.
Anyway, I'm really tired of sounding like a broken record so I'm going to stop here. This is just a "for the record" post.
