This is a very interesting product and I am glad that you mentioned it. 
However, I think I would rather use a cheap thumbdrive, strong 
passwords, and a Knoppix CD. Total cost = ~$30.

If you must have a biometric scanner for security, there are much 
cheaper ways to do it. I just found a 512MB Sandisk Cruzer Profile for 
$55. It is a thumbdrive and a fingerprint scanner combined. Add a 
Knoppix CD and you have the same functionality as this device. Except 
the BlackDog only has a 400MHz PPC CPU and 64MB RAM. This is probably 
slower than the host computer will be and it probably has less RAM too. 
Also, everything like networking, video, and disk activity must be 
squeezed through the USB bus when you use this device. With Knoppix, you 
use the PCI and AGP busses of the host computer for these things. 
Knoppix should be much faster than this device for most purposes.

Although this is an interesting product, I don't see how someone would 
use it as a "Wearab le" computer. It requires a host computer to provide 
input and output devices as well as to provide electricity. The only 
heads-up display glasses I know of have to be connected to a VGA, NTSC, 
or PAL video source. It doesn't look like this device can produce these 
signals. If you wanted to wear this, you would need to connect it to a 
sub-notebook running Windows or Linux and carry them both around. But 
then why not just put Gentoo on the sub-notebook instead?
