Windows XP to see double

News.com reports:

Microsoft plans to retool its Windows XP operating system so that two people can run applications on the same machine concurrently, an important step toward the company's goal of transforming the PC into a home entertainment center.
Service Pack 2 of Windows XP will let one person manipulate applications via the keyboard while another person views pictures or surfs the Internet on the same computer via a smart display, according to a source.

Cool but not cool. Why? Check out the prices for SmartDisplays. With around $1000 dollars for a display they are too expensive for me. I would rather go for a Tablet PC which we are contemplating buying for some time.
