I really like this article...

There is also a video on google.video talking about the same subject from Barry Schwartz author of The Paradox of Choice.

Since there's no way to post a reply in the article, here's my response to a bit in the end of the article: "Why do you want the power off? If you're concerned about power usage, let the power management software worry about that. It's smarter than you are." Let me just hit the magic button, pick up my machine and walk out the door with it. Oops! I tripped over a power cord. Unfortunately because the machine is "smarter than I am", it hasn't parked the drive heads yet because it hasn't been long enough since I pressed the magic button. Let's hope that nothing got damaged.

This post, while it highlights the problem of too much choice, is naive.
