I strongly agree and my entire laptop is encrypted.  Perhaps people could
consider suggesting to their management that data protection is critical and
disk encryption is a simple effective step.

Is *everything* on your laptop work related, or do you (speaking generally) sneek a few personal files on the laptop.

If the latter, what are you plans on transferring that info to/from other personal devices, such as a hime computer, a PDA, or another device?

If this policy you suggest is taken only a little bit too zealously, your company will mandate encrypting your work files, create and perhaps enforce a policy that only work related files are on your work owned laptop, and prevent things like synchronizing your calendar on your laptop and PDA, or other useful and harmless activities...

I don't like this slippery slope (of my org making this choice)

Sometimes managers aren't aware
of the tools (or risks) available and maybe it is up to the technical
community to inform them and help protect sensitive information (e.g.,
individuals data, company and client confidential data, etc.).

I would not recommend encrypting the entire laptop. As George Carlin
would say (*), border service agents with a double-digit IQ and a
triple-digit income might think that if dude encrypts the entire laptop,
dude must really have top-secret stuff on it, while the only two
confidential files dude has on his laptop are the payroll spreadsheet
showing how much more dude makes compared to his office buddies and
dude's mistresses phone numbers (one in each city, needs a database to
keep track of). No need to trigger un-necessary scrutiny: Traveling
Terrorist's 101: do not look, dress or act like one.

Besides, there are several ways to carry confidential info while flying.
Here's an example: They'll look at your laptop, but will not bother
looking at the 4GB SD card you have in your digital camera, which
happens to be a perfectly good plug-and-pray disk for any computer, PC
or Mac. I have stored Excel and PowerPoint files both in and out of the
directories used for pictures and it never bothered any camera I had in
my hands.

And even if they do look at it, there are ways to embed your
confidential data within pictures. You need to use a lossless
compression format such as TIFF. If done correctly, on a digital camera
with a noisy CCD at high ISO settings, there is no way to find out that
the least-significant bit of the picture contains actual data. A
5-megapixel 24-bit picture is 15MB, out of which 1.8MB are useable in
theory and 300KB in practice. In short: configure the camera to TIFF,
noise reduction to off, ISO 400 or higher.

Heck, you don't even need a laptop. Just a digital camera.
