just throwing in some xbox360 vs ps3 comparison stuffs...
Buying:
Xbox 360: cheap at first, but gets expensive in the long run if you play online.
PS3: More expensive at first, but cheaper in the long run (free online multiplayer being a plus), games are, however, a tad more expensive unless you usually rummage through the budget and pre-played shelves as I do
Hardware:
Xbox 360: Newer models are quite alot more reliable than the older revisions, and the slim version is quite silent. The older (white) one suffers from a quite noisy dvd drive, and extra harddrives for the old version are incredibly overpriced.
PS3: A bit more powerful hardware, you get a blu-ray player and harddrives can be upgraded with off-the-shelf laptop harddrives up to 500 gigs afaik (I upgraded my 40 gb to 160 gb just recently). In the "phat" version, the fans get a bit noisy if you use the console in a warm environment,
Controller:
Xbox 360: The 360 controller is quite brilliant for FPS games actually (having grown up on WASD and mouse myself), for racing games, it does a very good job as well. However, it's quite flawed and far too sensitive once you try playing 3rd person games and sidescrollers.
PS3: I find that the PS3 controller sucks for FPS games, but for the rest, it does a keen job
Online (monetary system);
Xbox 360: You must exchange your money for MS's toy money and it's hard getting your credit card deleted from the MS servers once they're entered (at least in some regions). Buy point and live gold cards, as they are usually cheaper in stores and on the internet.
PS3: Everything is listed in dollars and cents (at least here), and you can easily sign up with multiple accounts for different regions.
Online (game store)
Xbox 360: MS are quite restrictive on some factors of arcade games, even though many are quite fun. There are tonnes of games to choose from, and the store is easy to navigate. You can also watch ingame videos and see ingame screenshots for every single one of them. Also, there's only ONE special offer per week, and it's usually either for a sh***y arcade game or a Gold subscription.
PS3: While the amount of games on here are quite few (The PS3 is harder to develop for because of more complicated hardware), there are also fewer limitations on what you're allowed to sell. Some games (Wipeout HD and Fatal Inertia both being good examples) could easily be passed off at store-sold games. They also have multiple weekly offers on a few games (some of which you can get for free if you have a PSN plus subscription). The store interface does, however, take some getting used to.
Online (ingame)
Xbox 360: Beware of some of the larger games (halo 3, CoD), as their lobbies are most probably overrun by n00bs, less popular games tend to "die" online and you'll have noone to play with... It's very frustrating if you're a budget bin gamer like myself.
PS3: multiplayer in games doesn't die out as fast on PSN, maybe it's got something to do with the fact that Sony doesn't charge a penny for online multiplayer
I haven't encountered any of the more prevalent types of n00bs yet (mic screamers, idiot 12-yr-olds etc.)
buying tips:
Xbox 360: Get the slim version with a harddrive. If you want Kinect, go for a bundle
PS3: In this case, i'd say go for an older model, at best the 20 gig or 60 gig model. Those two models have the plus of being able to provide 100% hardware emulation of the PS2, meaning you can also play PS2 games on them
