HP's long-delayed Slate 500 has surfaced in an unofficial video (below) with unique details of how it works. The 8.9-inch Windows 7 tablet has its own dedicated controls to make up for the lack of a true tablet interface in Microsoft's OS. It includes both a button to bring up an on-screen keyboard at any time as well as a reported "Ctrl-Alt-Del" button to load Task Manager or reboot the Slate after a crash.
