The Samsung Focus, which previously went under the name Cetus or Omnia 7 (correction: the European Samsung Windows Phone 7 launch device will be called the Omnia 7), has a large 4.0″ WVGA AMOLED display that not only looks fantastic but has a high level of sensitivity (greater than any other Windows Phone 7 device we played with today). It’s also one of the thinnest smartphones in the world, and boy does it feel light in-hand. The Focus also seems to be one of the most snappy Windows Phone 7 devices of the nine that were launched today: jumping between screens was very fluid, and panning through the Start screen with an above-average amount of tiles was a breeze. We’d credit that to the 1GHz Snapdragon CPU, but all of the devices have the same chip, so perhaps this is a result of good software optimization from Samsung. Look for the Focus November 8th for $199.
