@marioguzman I vividly remember the complaints about the design changes. Many users didn't like the opaque global menu bar, also many thought the 3D dock took too much space and there was a command line work around to restore the 2D dock. In fact, even after many iterations they end up switching back to a 2D dock in Yosemite. When I play with Leopard though what I realize is it has too much gray tones. Tiger was just right.
