Pay no attention to the predictions of Gardner and IDC. Neither are ever correct. According to them, PC sales should have begun growth three years ago. Nothing that's been happening is close to their predictions. I predict that PC sales will plummet about the same amount next year, and the year after that, because that's what's happening. I agree though, that tablet sales are falling. Apple, for example, is finding that it's iPad 2 is good enough for many people, and with them having supported it with the latest iOS update, there is little reason for many people to upgrade further. Interesting because that is the last non retina screen model. But this year, likely iOS 10 will drop it. It will be interesting to see what happens then.
