The Android tablet is like one of those genetically engineered super-species from a sci-fi thriller. Each successive generation is smarter, faster and bigger than the one before it, and the pace of evolution gains momentum with each iteration. The Dell Streak (6 verdict, August 2010) wasn’t a viable challenger to any device in the tablet universe, but the Samsung Galaxy Tab (8 verdict, December 2010) showed the potential of what an Android tablet could be. Now the Motorola Xoom—almost a defacto reference design for the new Honeycomb OS—emerges as an evolutionary leap forward, and a direct threat to the iPad’s top-of-food-chain status.
