Virtual OS under Windows - I've just watched a very interesting half hour video from Channel 9 - the internal MS Dev TV channel. Ben Armstrong is the product manager for VirtualPC which is the product that was previously made by Connectix. I've been monkeying around with VMWare as an alternative to dual-booting my laptop with Suse 9.2 (best current distro of Linux). Anyhow - watch the video and check out the order they verify the functionality of a new build. It first has to run DOS, then Doom, then Quake, then Windows 95, and then if it runs Win2K they are pretty much home. They also give some interesting insights into why BeOS and O/S2 are so hard to provide under emulation (both for entirely different reasons).
