That's definitely the Apple model, and it applies so long as the tablet market is the iPad market. That will continue to be the case for awhile, but the tablet's conceptual proximity to the desktop (even apart from its forced convergence by Microsoft) is going to make its evolution more complicated than the smartphone market has been with its proximity to the younger, less baggage-heavy mobile / PDA market.
