5. Screen Sharing: Remote Desktop Connection
In Mac OS X 10.5 Leopard, Apple added the little known but useful Screen Sharing program (found in /System/Library/CoreServices/), also usable through iChat. Screen sharing lets you view and control another networked Mac running Mac OS X 10.4 Tiger or later. Windows users have had this functionality in Remote Desktop Connection since Windows XP. In fact, Microsoft provided a free Mac version of Remote Desktop Connection before Apple added the functionality to Leopard.
