I have certain misgivings about Vista resembling Mac OS X. With its translucent windows, such comparisons are going to be hard to avoid. But Vista's similarity with OS X goes well beyond window dressing. Certain applications, such as Calendar, Sidebar, and Photo Gallery, appear to be directly, ahem, influenced by similar applications in OS X. Microsoft has a response to that claim, which I'll reveal in part 3 of this review, but suffice to say they're going to get eaten alive for these similarities.
