Wow. This looked so good on Lifehacker, but in reality, it’s useless. What it’s supposed to do is use sonar to detect your presence and put the computer to sleep when you’re not there.
I have to admit, it does work, but a timer is just so much more convenient. The first problem is that it’s not terribly accurate. If you lean back in your chair, it will shut your screen off, but if you leave the room and your chair is in front of your computer it won’t do anything. The second problem is that there are virtually no options. It’s either on, or off. You can’t change anything. The third problem is that it won’t wake up when you sit down. It waits for activity and presence.On the bright side, if there’s an earthquake and your mouse moves, it won’t wake up the computer. In the end, it doesn’t accomplish anything a timer can’t.
