Snow Leopard

I am bit nervous about the new operating system from Apple, Snow Leopard. I know MacOS is "better" than Vista, however using at work Windows 7 RC for the last few weeks showed me that Microsoft learned something and created really solid piece of an operating system. I am bit worried, that new, improved Snow Leopard may simply not be enough of an upgrade to win with Windows 7. Time will tell of course. In the meantime I'll try to put my hands on Snow Leopard preview build, to see how much actually changed...
