Controller vs. mouse and keyboard? Not a fair match.
With gaming technologies so similar these days, as games use the same engine technologies, it would seem like a logical step for different platforms to be able to play with each other online. After all, Macs and PCs have been harmoniously getting along with each other online. So what about consoles?
Microsoft controls what goes on its Xbox 360 platform, so through its Games for Windows initiative, one would assume that Microsoft at one point must have contemplated getting its console gamers online with PC gamers. According to VoodooPC founder and HP CTO Rahul Sood, Microsoft tested it and then canned it.
Why? Because console gamers were no match for PC gamers.
"There was a project that got killed at Microsoft. This project was designed to allow console gamers and PC gamers to interact and battle over a connected environment," Sood wrote on his personal blog. "I've heard from reliable sources that during the development they brought together the best console gamers to play mediocre PC gamers at the same game... and guess what happened? They pitted console gamers with their 'console' controller, against PC gamers with their keyboard and mouse."
The results shouldn't be too surprising.
"The console players got destroyed every time," Sood added. "So much so that it would be embarrassing to the XBOX team in general had Microsoft launched this initiative. Is this why the project was killed Who knows, but I'd love to hear from anyone involved --- what happened?"
Sood then continued expressing his belief that cross platform play with the Xbox 360 would promoted the PC as a superior gaming platform, with a little nudge to developers to consider looking at making games for HP's newly acquired Palm webOS.

As it stands, I use both a 360 controller and Mouse+key combo on my pc. Mouse and keyboard cannot be beaten for fps. This has been talked about for the last 8+ years and this keeps going on and on.
But, as I first stated, if you're rubbish then no controller will help (But extreme auto aim might
Yes.
If you have to ask... it's best if you just keep playing your console.
i think it'd be great for xbox live to work with pc games though, could open up revenue for microsoft in mroe xbox live subscriptions and in turn it could result in less hacking in pc gaming durring online play; now i'm not sayign only allow it via live, just an option and merging players would make for some interesting chatter... you could tell the xbox users by the slew of F bombs and thier voices periodically cracking due to having just hit puberty... you could tell the pc gamers by looking at leaderboards
Yes.
