Microsoft made a lot of announcements today, but one of the things it didn't talk much about was the giant, 82-inch, pen-friendly PC that the company used to demo some Windows 8 features. It's a Perceptive Pixel PC — Perceptive Pixel was founded by Jeff Han, who at TED in 2006 demonstrated touchscreen interfaces that were remarkably ahead of their time. It's a Gorilla Glass display, and is also touch- and pen-enabled; this thing puts the Galaxy Note to shame. It's just one of many devices Microsoft showed off, as part of its proving how many different types of devices can use the new operating system. Windows 8 even powered two of the enormous displays, running well over 100 inches of monitor space on a single PC.
