Paul Thurrott from SuperSite for Windows decided to compare Apple's Mac OS X Tiger with the first beta version of Microsoft's Windows Vista.
Too, I'd like to remind you that Windows Vista is only in Beta 1. Lots of things are going to change, and many, many features will be added by Beta 2 and beyond. This stands in sharp contrast to Apple's approach with Tiger. If you go back and look at the WWDC 2004 keynote video, you'll see Steve Jobs demo virtually every single major new feature in Tiger. A year later, when the product actually shipped, little had changed and nothing major was added. This isn't how Microsoft works. Beta 1 is a minor subset of the overall functionality we're going to see in the final Windows Vista product.
OK, let's see how Mac OS X Tiger and Windows Vista Beta 1 stack up.
