Here is an interesting video. It shows a single game being played on Windows, XBOX360 and Windows Phone series 7!

Microsoft’s Eric Rudder, speaking at TechEd Middle East, showed off a game developed in Visual Studio as a singular project (with 90% shared code) that plays on Windows with a keyboard, a Windows Phone 7 Series prototype device with accelerometer and touch controls, and the Xbox 360 with the Xbox gamepad. Interestingly, not only is the development cross-platform friendly, but the game itself  saves its place and lets you resume from that spot on whichever platform you happen to pick up.

That last bit sounds very interesting! Being able to continue a game nomatter where you are would be a very nice feature.
