Be Careful

This is a fantastic way to burn out the screen. Most of the heat from the laptop is released through the keyboard. Ever seen a laptop that didn't properly sleep when someone closed the lid? We've had several here, and they were all very expensive to fix. The screens were fried and had to be totally replaced. Apple's new laptops are not designed for this.

Hard Drives are robust, but...

IMHO, carrying around a running PowerBook (heat issues aside) is just not a good idea. Take a look at some of the specifications for Hitachi (IBM) or Toshiba's laptop drives. The operating specification for the amount of motion (shock) they can sustain is only about 12% of the non-operating shock. (200Gs-2ms vs 800Gs/1ms on Hitachi TravelStar drives) I'd definately not recommend putting your 'book in this headless mode to carry it around.

Hard Drives are robust, but... - More then you would think

You're right about the paper specs on the drives but...
I know from experience that the amount of abuse and beatings a standard harddisk can take is simply unbelievable. Take any laptop - You can shake it and throw it around and drive around with it powered on under your carseat, and it normally just keeps going.
Of course you should be insured and make regular backups ;-)

It's only under the most extreme conditions you should go for a mil-spec ruggedized laptop (to bad Apple doesn't make such a thing, there's definitely a market for those bastards)

It also depends on what the drive is actually doing when it's taking a beating. If it's trying to write something, you might lose some data... but I think head crashes are pretty rare these days. ;c)
