Ok but it's much nicer having an icon I can quickly click which also visually shows me if it's keeping the computer awake. It's very easy to choose different amounts of time to stay awake, including giving it a specific end time rather than a duration. And the little audible alert when the time expires is nice for letting me know it's over so I can decide if I want to add more time. Plus it has an option to prevent accidentally draining the battery to nothing by letting the system sleep if it drops below 10% battery.
