Essentially, the My Location feature takes information broadcast from mobile towers near non-GPS equipped mobile phones to approximate the device's current location on the map down to about 10 city blocks. "It's not GPS, but it comes pretty close (approximately 1000m close, on average)," the Mountain View, Calif.-based search giant explained on its website. "We're still in beta, but we're excited to launch this feature and are constantly working to improve our coverage and accuracy." The My Location feature is currently available for most web-enabled mobile phones, including Java, BlackBerry, Windows Mobile, and Nokia/Symbian devices.

By playing out every possible move — about 500 billion billion in all — the computer proved it can never be beaten. Even if its opponent also played flawlessly, the outcome would be a draw.
