ZDNet columnist Mary Jo Foley says that Leopard looks a lot like Windows Vista and goes on to compare Apples latest OS to Windows Vista: "Instead, it was the excitement by the 5,000 WWDC attendees about many technologies in the forthcoming Mac OS X Leopard release that already exist in Windows Vista...a list follows"

Looks like the author obviously has no knowledge of the subject matter. First of all, Apple announced many of these features before Vista was ever released, so Microsoft probably just ripped off these features for Vista, it's what they do best. Second of all, Vista is extremely buggy, and Leopard looked really stable. Also, flip 3D is only to view open windows, sort of like expose, and it has nothing to do with viewing files inside of folders. Quicklook allows you to preview multiple slides in keynotes, and multiple pages in PDFs, thumbnail view does not allow any of that. Also, there is one version of Leopard that is optimized for both 32 and 64 bit apps, and even though there is a 32 and 64 bit version of Vista, it is only optimized for one or the other, not both. Dashboard and widgets have been around for awhile in Mac OS, and the sidebar and gadgets in Vista are brand new, another rip off of Mac OS. Also, there were features demoed off like stacks and spaces that are not available in Vista. Last but not least, you are forgetting the most important thing, Steve only demoed off 10 of the 300 new features of Leopard. It would be nice for at least one person at ZDNet to know something of alternate OSes before attacking them...:] Ugh oh, I feel a huge flame fest coming on :-)
