Not sure how a nearly 30% YOY increase in tablet sales for Q4 translates to a dead market, unless they thought tablets would end up as full replacements for existing systems. Few people are replacing their other computing devices for tablets, but obviously a large number of people see, and will continue to see, tablets as good secondary devices. I suspect, however, that replacement cycles for tablets will be longer than for phones (which cycle out on contracts) or PCs (driven by corporate platforming schedules). Anecdotally, I lug around a smartphone, laptop, iPad and Kindle, but I can collapse the last three into the iPad for a lot of daily nontechnical tasks. (Hell, I can even prototype Python on it.) It's not a necessary part of my kit, but I'll keep one around for convenience alone.
