It is highly responsive, very reliable and predictable, can be used with only the keyboard, can be configured easily, can be introspected readily, and is also very flexible and general: For example, it can be used as a display engine for almost arbitrary interactions including calendars, games, spreadsheets, can incorporate output from other programs etc.
Importantly, it provides elegant means to automate all tasks it can do.
