One of my colleagues Dave used to say that the security experts at his former employer advocated carrying a laptop outside in a sturdy carrier bag rather than the dull holdalls that come free with Dell laptops as these gave a subliminal message to career criminals, drug fiends and listless teenagers that said 'Take me please, I'm all yours'. So they would approved of Humanbeans 'Power Pizza' box, a pizza box with foam and securing straps to securely hold your prized PowerBook.
There is also a certain symmetry as pizza boxes are often left lying around as IT people solve network problems and do all-night coding sessions fueled on slabs of pizza and the most highly caffeinated beverages of their preference.
