Your comment reads like something from a year or two ago. The "there's an iPad market, not a tablet market" part of it really gives it away. The Kindle and Nexus markets have been selling very well, and the iPad is reduced to only half of the market now.
Your main point, too, sounds like something from before tablets have really started gaining momentum. I actually have seen directly many people, including many of the older generation, where tablets have really completely supplanted PC's in their lives. My mom who used to use her computer for nothing except light web and email hasn't touched her computer in a year now that she's gotten a tablet.
