SoC =/= APU. A true APU woud be completely homogeneous - you shouldn't be able to tell where the CPU stops and the GPU takes over. The ARM market is too segregated for that kind of integration and unfortunately AMD is our only hope for a true APU right now. Let's just hope that they do better than the botch job that is BD.
