BIKER4MAC  For the simple act this program performs, not only does it perform it well without a clutter of "extra" and unneeded features, but one doesn't realize how useful this simple act can be until they start using Caffeine.

I use my computer off and on throughout the day. So things are set so that if I'm away for more than a few minutes the screensaver clicks on. If I'm away for fifteen to twenty minutes the computer goes to sleep. Based on my work habits, that works well for me.

But getting into the system preferences to deactivate the screen saver and sleep mode if I'm doing something without input for awhile gets to be a pain. And although iTunes deactivates these settings if you're watching a video, watching something online with a browser doesn't have that benefit. South Park online is a guilty pleasure, I must admit.

So Caffeine's little coffee cup sits in my menubar and is very easy to click on when I need it. If only it were that easy to keep myself awake and alert for those late night pushes for a deadline!

DRDUL  What a useful little app! The addition of a setting for a default duration makes this even easier to use.

JOSH RODGERS  I downloaded this software so I wouldn't have to change my system preferences every time I wanted to watch a movie.

This little app is excellent! It was exactly what I was looking for and program use couldn't be simpler. Just click on the coffee cup and that's it! Returning to regular mode works exactly the same! It's a great little free program.

Simple, straight-forward, easy to use.

AYUB  Great! Was looking for it. Sometimes while reading a complex document relaxing on my chair I need the sleep/display-sleep disabled without going to PrefPane. This application does exactly what is needed in such cases. Keep it up. :)

AV  Very useful. I seem to use it all the time and generally only turn it off at night so i can sleep the display if im listening to something as i fall asleep or leaving something to download/upload overnight.

JADDER  This is a great little program that does exactly what it says. I find it very useful to use when giving presentations.

OAK  Have you ever heard the old saw, "Never look a gift horse in the mouth"? Caffein is FREE. When one pays for an App one gets the right to complain about it.

JR23  This is a wonderful little utility. I frequently attend webinars, and use SnapzPro to do a video capture. I would always forget to turn off both the screen saver and power saver (I'm on a MacBook, 10.5.7) at the beginning of the webinar. Now, I just click the coffee mug in the menu bar, and I'm good to go.

Feature request: this is probably a whole other can of worms, but I'd love a single-click utility with Caffeine's function that also includes the option to pause things like iCal alarms, system alerts, etc. In the meantime, anyone know of a utility that does this other function?

HALEAKALARI  there seems to be a minor interface glitch with this version of caffeine (1.0.4). under os x 10.4.11, when command clicking on the icon, the submenu which allows one to activate caffeine for a specific period of time, does not display text. just thought i'd let you know.

UMIJIN  Hmmm - new download doesn't seem to have a way to install. Can't quit the menubar applet to allow a drag and drop replace.

No info I can see on the developer site on how to update, AFAIK.
