From Ars Technica: "The enterprise targeting is also apparent; there's a dedicated ctrl-alt-del button, to accommodate the Windows default of requiring the magic keystroke to log on in domain environments."
Great. This is exactly why I avoided mentioning corporate login in my defense of the Ctrl-Alt-Del button on the HP Slate, for which I am now getting bashed. I log in to a corporate server every day. I know why Ctrl-Alt-Del is needed. What I didn't want is for the button, which should be standard on every Tablet PC, to be equated with corporate and enterprise use. Oh well.
