Motorola’s long anticipated unveiling of the first Android 3.0 Honeycomb tablet, now dubbed the Xoom, along with the introduction of its first 4G dual core 1 GHz + 1 GHz processor phone, the Atrix 4G, might have been trumped by an unexpected and unique accessory: a keyboard/11.6-inch screen/battery dock. By snapping in the Atrix into the rear of the otherwise dumb “dock,” you get a 2 GHz 4G-connected notebook PC running Android.
