DEMOfall 07 Browser/OS Statistics

Stephen Wildstrom did a little survey of demo machines at DEMOfall 07. 81% Windows, 19% Mac. He says that’s growth, and I’m not shocked to hear that. He also did a survey of browsers and found all Mac’s use Firefox over Safari, and makes a reference to it’s skin (an interesting observation considering the current discussion over reskinning the browser for 3.0). Firefox did decent on the Windows front as well. I’ve noticed this myself. People seem to prefer demoing their web based product in Firefox. Is it out of habit? Or because some ajax based websites feel slower in IE7?
