Newsweek did an interview with Bill Gates, questions about apple comparison etc.
In many of the Vista reviews, even the positive ones, people note that some Vista features are already in the Mac operating system.
You can go through and look at who showed any of these things first, if you care about the facts. If you just want to say, "Steve Jobs invented the world, and then the rest of us came along," that's fine. If you’re interested, [Vista development chief] Jim Allchin will be glad to educate you feature by feature what the truth is. I mean, it’s fascinating, maybe we shouldn't have showed so publicly the stuff we were doing, because we knew how long the new security base was going to take us to get done. Nowadays, security guys break the Mac every single day. Every single day, they come out with a total exploit, your machine can be taken over totally. I dare anybody to do that once a month on the Windows machine. So, yes, it took us longer, and they had what we were doing, user interface-wise. Let’s be realistic, who came up with [the] file, edit, view, help [menu bar]? Do you want to go back to the original Mac and think about where those interface concepts came from?
