Yes, you read right. I have got my hands on the actual beta of Mac OS X Leopard. In this beta, Spaces and Time Machine are built into the OS, so there are no icons on the dock for them. If you look at Spotlight, you can see that if you type "dictionary" and then a word, Spotlight will show the definition of that word. As you can see, there's a new icon on the dock, and a new menu icon in the menu bar. Both are used to control the Windows Environment, which operates very similarly to the Classic Environment on PPC Macs. Obviously, this feature is not compatible with PPC Macs. It uses your Boot Camp installation (though as of this beta, Windows Vista is not compatible) and runs your Windows apps alongside your Mac OS X apps. You can also see the iTunes 7-esque interface has almost completely replaced Aqua. Sorry about the screen shot though, Apple doesn't seem to have any sort of screen capture utility in this beta, possibly to avoid any leaks.
