Here's a good article detailing the 3way action (another one at NYTimes, thanks TheOccifer) going on between Sony, Microsoft, and Nintendo in the console wars. If you consider yourself a gamer (or a human being) you no doubt enjoy the very concept of 3way action.

market leader Sony has built a strong bunker against the interlopers, having shipped more than 20 million PlayStation 2 machines since its debut last year [...] Microsoft plans to spend $500 million to market the Xbox during the 18 months after launch, while Nintendo is budgeting $457 million for marketing this year for both GameCube and its new Game Boy hand-held player. [...] Sony is suffering one of its worst financial periods ever and can't afford an expensive battle with cash-rich Microsoft

Also, a few people have noted that there are fully playable XBox systems at a few computer stores with the full versions of Halo and other games available to play.
