I think that "power users" grasp the target audience bit perfectly well, and are okay with simplified tablets. What they would like to see are tablets that reflect their interests in computers. Tablets fill the computational and memory requirements of much more advanced applications. Vendors can produce tablets both with and without external expansion. In other words, both markets can be served.

And please stop talking about iPad as the pinnacle of tablets. It isn't. Just as Android isn't and Windows 8 isn't. Each of these products address different markets. You have an iPad for reasons of your own. I have an Android for reasons of my own. Microsoft has introduced the Surface to address the needs of markets that aren't being served by the iPad and Android tablets. In a marketplace that will ultimately reach the billions, there is plenty of room for competition.
