I'm not really into portable systems so no...I've had a PSP for years and I've barely used it, although I will admit the Socom games were very fun on it.

I thought Microsoft already had a portable, called Windows Phone.

Hey, the mobile gaming market is far larger than the 3DS and Vita combined!

I would love an Xbox portable. Something like this would be ideal

Not interested in that.

We already have one. It's called Windows Phone.

No, it would probably end up worse than the Vita is right now.

There is already, it's called Surface

If it was also a phone yes.

Otherwise probably not although it all depends on price, hardware and software.

Halo, Gears and Fable would all make for brilliant handheld titles.

If we want to see something flop worse than the Vita (if that's even possible), then sure.

As many have said, the games Microsoft brings to their home consoles do not translate well to handheld console games. I just don't think there is a market for it.

I really don't think a Xbox handheld system would work too well.. :/
