Apple has apparently perfected their Windows emulation:

Dreaded Blue Screen of Death mars some Leopard installs
Apple support drones are getting an earful from Mac users who are getting the dreaded Blue Screen of Death while trying to update to the latest and greatest version of OS X. This thread on an official Apple support forum has more than 200 posts left in 25 hours at time of writing. A large percentage of the writers report getting a persistent blue screen that forces them to abort their installation of Leopard.

I cannot help but be amused. I kinda like Apple, but Steve Jobs' arrogance gets to me. This will take him down a peg or two -- hopefully.
