.Mac Sync Improvements
A .Mac account has made it possible to synchronize some settings across multiple Macs for quite a while. This is a huge convenience when you have more than one Mac—perhaps a desktop Mac and a laptop Mac, like me.
Leopard now enables you to synchronize more settings, including Dashboard widgets, Dock items, and preferences. This helps "standardize" the interface of your Macs, making it easier to switch from one to the other when you need to.
