Software from apple that assists in installing Windows on a new intel-based mac.
This is cool, but for my web/development work it's not a viable option. I need Windows and OS X side by side at the same time (not one or the other at boot time.) I use Microsoft Virtual PC to accomplish this now on my G5, but there is new software coming to the Intel Macs soon which will run Windows at "near native" speed alongside OS X. Droooolllll....
