Windows 7's "XP Mode" is little more than a bullet on a feature sheet. In other words, it's designed to get people to buy into Windows 7 (AKA Vist WOW!, Part II). Issues with XP Mode include: (1) Will your apps run at all? Will they glitch?, and (2) You will likely not get the performance and responsiveness you are used to, since everything running in XP Mode runs on a *single* core only.
So XP Mode is more accurately named "Might work in limp-along mode", but that would be a marketing blunder, wouldn't it?
