Doing the same thing over and over again is a boring chore. Windows and Mac understand that, that why they have the automation program built into their OS. Windows XP & Vista have a task scheduler that allow you to create and automate simple task. Unknown to many, Mac OS X iCal alarm function can also be used to schedule and automate task.

In Ubuntu (or basically Linux), task automation used to involve writing shell scripts and setting cron job, and this is not an easy thing for a new user to do. Luckily, there is the Gnome-schedule that come with a simple graphical interface and makes task scheduling a breeze.
