For many Mac OS X users migrating from Linux or Unix, the Terminal application is a frequently used piece of software.
However, the native Terminal application leaves much to be desired, most notably due to lack of support for a tabbed interface. For an improved Terminal emulation utility, consider iTerm, a native Cocoa application that supports both a tabbed interface and transparent windows. Since the application is written in Cocoa, it maintains the standard look-and-feel that numerous Mac users have grown to love. iTerm is a free application and supports all of the same language encodings available natively through OS X. Try out this fantastic find at http://iterm.sourceforge.net, where iTerm is available as a convenient universal binary.
