Yes, programmable shaders is one of the most fundamental aspects of this generation of tech, the first GPU's supporting it arrived in 2001. But the Wii released 5.5 years later doesn't support shaders. YUCK!

Edit:

With the introduction of Move and Kinect it will have exactly one advantage: Price. Which is not an advantage that applies to those that have multiple systems.
