Apple in a “clean-up” phase, preparing for new generation of computing?

I recently wrote an article on Apple’s seeming lack of real innovation in the Mac market. After some consideration, I realized that all of their product lines have been rather stagnant lately: iPhone 3G was a small departure from iPhone design-wise, Macs took on a gray and black finish, and Snow Leopard is supposedly not introducing many new features. This leads me to believe Apple is preparing a new generation of computing.
