If Apple ever releases this device, I will buy one and eat it publicly on YouTube.

I just don't see the point. A4 tablets have specific niches in which they make sense, such as in hospitals or warehouses, but for everybody else they're just too big and clunky. Why would anybody want such an unportable device that lacks a keyboard?

Also, Apple's chief business plan for the last 10 years has been built around multimedia and the home user (iPod, Apple TV, Mac Mini). How will an A4 tablet fit in with that? And Apple tend to be innovative but how could they make an A4 tablet any less of a disaster than it already is? The A4 tablet form factor is broken. There's nothing you can add to it to make it work. You can't simplify it to make it any better, which is how Apple usually works.

Now Apple might be considering producing an smaller tablet but they've effectively already done that with the iPhone and the iPod touch. But they could easily produce a Nokia Internet tablet competitor -- a dedicated internet tool with Flash, Java, full media support etc. My prediction remains that they will do this within five years and pretty much blow Nokia out of the water.
