The tablet hype could burn out soon, but I don't think notebook PC demand will come back to historical levels as if they are missed. Many nonPC habits have been generated with tablets, it's going to be hard to break.
Well, IMO this "resurgence" was bound to happen sooner or later. It couldn't take forever for the average joe to realize that tablets are not useful in the same ways that PCs are, and that the giddy excitement over the new toy did not mean the PC was now rendered useless. As the term "post-PC era," trumpeted so often by the press, seemed to imply.
I've seen good things about the desktop version of Win8, believe it or not. Apparently, many of the complaints are not entirely valid. Although it is possible that the "default" settings might be more to the liking of tablet users than desktop or laptop users.
