High Resolution Google Chrome Book

Google is adding a new and more expensive touch to its line of Chrome laptops in an attempt to outshine personal computers running on software made by rivals Microsoft and Apple.

The Chromebook Pixel unveiled Thursday includes a nearly 13-inch display screen that responds to the touch or swipe of a finger. That duplicates a key feature in Microsoft’s Windows 8, a dramatic makeover of the world’s leading operating system for PCs.

The Pixel’s high-resolution screen displays 239 pixels per inch, slightly more than Apple Inc.’s MacBooks with high-resolution Retina displays. A MacBook Pro with a screen that measures 13.1 inches diagonally can handle 227 pixels per inch
