Microsoft has unveiled one of the biggest features planned for Windows XP's 2nd Service pack.
According to sources, SP2 will let one person use a computer normally using a keyboard/mouse while a second person will be able to use the same PC's resources to surf the net, look at pics, etc. using a smart display, sounds like an evolutional step that makes a lot of sense to me.

[COLOR=royalblue]A smart display, which Microsoft developed under the code name Mira, is typically a 10-inch or 15-inch detachable monitor running Microsoft's Windows CE for Smart Displays operating system. They do not contain hard drives and do not connect directly to the Internet. Instead, they funnel requests to, and receive data from, a base station PC running Windows XP. Once detached, the smart display connects back to the PC using 802.11 wireless networking for accessing e-mail, surfing the Web or reading documents. A stylus, rather than a keyboard, is used to input data.[/COLOR]
