Bloody fanboys...
Both consoles have their pros and cons
Ps3 has more exclusives and variety in them:
Uncharted/Killzone/Ressistance/InFamous/LBP/God Of War,Ratchet And Clank series/Modnation etc
Xbox has:
Halo/Gears of War/Alan Wake,Splinter Cell etc (WHO ACTUALLY PLAYS VIVA PINATA?!?!?!)
(those are the ONLY I've heard of people actually owning)
Halo I've played a bit of and haven't liked it much, I just jumped around and sprayed and dominated, every now and then a vehicle would run me over and thats it, never played Gears but it looks pretty epic and Alan Wake I have no idea but heard it's pretty good.
Uncharted, amazing graphics and has good gameplay, but they ripped the MP off Gears :|
God Of War is just amazing in visuals and gore, if you have played Darksiders it's like that but 100000x more epic and has more variety in attacks
Ratchet and Clank/Modnation/LBP all ages games that are incredibly fun even though they are childish, I still am in love with Ratchet in Clank (not the new one, they failed with that)
InFamous = amazing in every way.
Ps3 is teamed with some companies,Xbox has teamed with some too, stop making a big deal about getting DLC on one game a month early, not everyone plays cod/cares about dlc, there are more games out there than Call Of Duty
Ps3 is free online, with PS+ to get discounts + free games along with other perks if you pay a fee, the online works fine and doesn't have many bugs as I've seen, only problems have been with the attack (only went on for a few days, the rest was Sony rebuilding PSN and adding security and that) and when a MW2 map pack came up and the server got too many requests and wouldn't let people add money to their account to purchase it.
PS3 also has catchup tv + Playtv which is pretty much a pvr for $90 and can be used to view and record the normal channels, the web browser I never use as I own a computer and that is next to me while I play PS3, but I don't really like the browser much since it's easier to just hop onto a computer.
Xbox you pay to get cross game chat, Foxtel (not sure if theres extra reqs for that) and also has Facebook + Twitter but as said above just get a computer, problem solved, you should be able to move to the next room to check your Facebook between games or whatever.
Xbox also (only I have heard, not 100%) can listen to music from the console while playing a game, but that is what an iPod is for
Obsessed with the Xbox controller and hate the Ps3 controller? There are Ps3 controllers which are designed almost exactly the same as the Xbox's, but when I tried to play on my friend's Xbox I just couldn't adjust to the thumbsticks that easily, have yet to see a ps3 styles Xbox controller.
Both consoles have kids and mature people, Xbox has more mics on it as (correct me if I'm wrong) the console comes with a mic, I just hate how you have to connect the mic to the controller, Ps3 most are wireless and just charge them, which goes back to controllers, Xbox you need to keep getting new batters (or just rechargable ones and a charger) and Ps3 you can just plug it into your computer/console for an hour and it's fully charged and ready to go.
Have I covered everything? I tried to make that unbiased, I haven't had more than a day of playing on Xbox so I can't judge everything, but as I said Playstation is for cheap people who just want to have fun, it is an all around console which is good for the whole family (blu ray player, all ages games etc) and can run games perfectly fine.
Xbox has cross game chat for that extra addition to social features (I just use Skype so eh) and has a pay for online service which makes it more reliable, you can get some early dlc for Call of Duty but as I said COD isn't the only game around.
