An article reviewing the 3 current consoles on the market interms on selecting one the best suits you.
"I feel that the Xbox 360 is the console to beat, as it is the most versatile, while offering a comparable graphics experience to what you'll see on the PS3. That said, I do have some concerns about the 360's reliability, so I'm going to recommend something I never do: Buy it locally and purchase the in-store warranty, so you can replace it immediately at any time free of charge.
If you absolutely must have the best pure gaming experience, the PS3 should ultimately win out, especially when developers begin to figure out how to unlock the console's most impressive capabilities. A year from now, I expect PS3 games to absolutely blow away anything available on the 360.
As for the Wii, I'm going to have to disagree with the consensus and call it as I see it: Unless you have very young kids with no video game experience at all, skip out on this console. The Wii is a joke, a novelty console that doesn't offer much staying power. Either the 360 or PS3 would be a better choice for almost anyone.
