Your PC, simplified

The TouchSmart advantage
Use your fingers for fast access to information, communication tools, and entertainment. The intuitive touch technology makes everything you do easier and more fun:

• Interact with the PC using your finger; your touch registers just before you make contact with the screen
• Use touch instead of a mouse to click and drag, and to navigate through music, photos, and movies
• Zip around your PC with multi-touch gestures such as pinch, rotate, arc, flick, and press and drag
• Interact with applications directly within a tile, without launching the app, and seamlessly run multiple apps
• Expand larger tiles to fit the new 16:9 widescreen so you have more real estate
• Personalize your touch background in two taps
