Sony's new all-in-one PC, the Vaio L Series Touch HD PC/TV, announced today at CES, reduces the number of fingerprints that typically cover most touchscreen displays by placing many of its controls along the LCD bezel. It does so by extending the touchable area of the screen to the black portion of the display.

Each control is located where you'd expect it to be. For example, you close windows by touching the top right corner of the screen, just above where the button would be displayed that you'd normally click on to close a window with a mouse. You can also flip through Web pages and zoom by using the outer touchscreen.
