In a sick way I really hope they don't release tablet just to make all of the constant rumors, speculation, and 4th hand information false. Especially the rumors that state "The Apple table will have...", when they have no idea.
I also believe that if they do release one it will be somewhat underwhelming in relation to all of the stock-pumping rumors, but still potentially cool.
If nothing else, I hope something is released so people will stop speculating about it.
EDIT: I had this post sitting around. Got busy and finally put it up, and just got to check out some live blogs. So far, it's exactly what I thought. A giant iPod Touch, with standard features available on every other computer/tablet, and the only thing "revolutionary" about it is it's Apple designed GUI. If anyone expected anything more then you haven't been following Apple releases for very long.
Edit: Not that it's awful, but just standard. The only thing that separates this from anything else is the UI, but that's pretty much the most important thing for a touch screen computer; and is the same reason the iPhone is so popular.
