Attached is a screenshot of my Wintel emulating Mac OS X via PearPC http://pearpc.sourceforge.net. It runs decently well, but operates slowly (as you might imagine). I had to create a disk image and install Darwin so it would work (the disk utility in OS Setup doesn't work in this case), and then I could install OS X (Panther, no doubt!) from disk iso images made from the original cds. I wonder how this compares to Virtual PC, although I'm sure it's not near as integrated as VPC is...well, actually PearPC isn't integrated at all without some tweaking. But it is no where near usable for productivity, however, if I created some small removable disk images, I could get data to and from my PC. I'm quite impressed though due to the difficulty in emulating the PowerPC processor...I remember the days of Basilisk II and Softmac...(they had such great claims at coming very close to emulating PowerPC processor, yet now their site is no longer in existenc) I also noticed some bugs in the OS GUI...for instance, if you will notice there is no shadow behind the 'Macintosh HD' text in the screenshot... Another good resource for mac emulation is http://www.emaculation.com. NOW, all I need to do is install iLife!
