There is an interesting question lurking behind this post. If a tablet does materialise, what will make it successful?<p>Is it something that could have been done much earlier or something enabled by recent (or impending) changes to available technology? Hardware for an iPhone quality smartphone was available a decent prices for a few years before it came out (especially if all you want is a phone that handles music and video pleasantly, not internet &#38; installable apps), but not many.<p>If Apple comes out with a tablet that succeeds because Apple has figured out the right use-cases &#38; metaphors for it, that might mean that they could have done it ten years ago.  That's something.
