Cloud OS. That thought scares me. Consumers are getting more knowledgeable about data. The cloud can be a scary place. A full blown cloud OS might be taking things to far.
Ms need to take a step back. Concentrate on what they did well. Produce an OS that meets consumer needs. Trying to catch up with competing systems (surface) is just plain silly. It's a pc, it does what it does. Mouse and keyboard work just fine until voice becomes a proven technology.
