One nice tidbit from the review is that you can replace Leopard’s new reflective Dock with a more functional one by entering the following commands at your terminal:
> defaults write com.apple.dock no-glass -boolean YES
> killall Dock
This will give you the same style of dock that you’ll get if you position the dock to the left or right of your screen, even if you put the dock at the bottom. If you change your mind, and want the new shiny reflective dock back, just repeat the above commands replacing “YES” with “NO”. The changes will stick through a reboot.
