Hybrid Power is the second major technology announcement with the new 700 series of chipsets for AMD (and eventually Intel). Most desktop applications do not require major graphics power, and even Vista's Aeroglass runs perfectly fine on integrated parts supporting SM 2.0 functionality. It makes little sense for a user with 2 high end cards in SLI to run them at full power when just doing desktop application work or surfing the internet. The only downside to Hybrid Power is that it requires that the discrete card supports that functionality, and currently no GeForce card features that quite yet.
