Actually, the difficulty is with the Cell processor inside the PS3 that makes it difficult for some companies to make games for the PS3 and not the blue ray. Xbox is not better for FPS'. i play MW2 on both and there is no difference. Graphix are about the same refresh rate is about the same, sound is about the same. The only things that 360 has over PS3 is the controller design and Halo. As far as gettting to friends lists and sending messages, its different between the two consoles but one is no harder than the other. I am more familiar w/ PS3 so it is easier for me. If I played more on Xbox it would be easy. This question has no right or wrong answer. So choose the PS3 and get over it. LOL. Game on, Brothers and sisters. see here about Cell processor.

Halo isn't even that great though. My favorite part of that game was it's forge mode and unfortunately it just doesn't hold up to the customization with games like ModNation Racers, LittleBigPlanet, and soon to be Gran Turismo 5. To be fair though, the games I just mentioned came out roughly two to three years after Halo. Custom games and forge is where its at with Halo, but not many utilized either to their full potential. As for the whole shooter argument, I have to agree, the multiplatform shooters have little difference from one another and plus, we have Killzone 2 (soon to be Killzone 3), Resistance 1 and 2, Uncharted 1 and 2, etc etc. Many upcoming multiplatform titles are also getting exclusive content with the PS3 as well as already existing multiplatform titles. You may get MW2 maps earlier than we do, but hey, we still get 'em. I got both of the map packs for free, too, so you'll hear no complaints from my end. Game sharing is nice and as I previously stated, the internet functionality beats out anything Xbox Live gives you, and you have to pay for most features with Xbox Live anyways. Don't get me wrong either, I'm not trying to justify my purchase, I know I made the right descision in getting the PS3, I'm just providing my opinions so that maybe others will give it a chance instead of immediatly dismissing it without playing it.
