I tend to agree with Macenstein: what do we need an Apple Tablet for, anyway? The whole ultraportable idea seems to be based on the fact that people want to see it made, not necessarily that anyone is walking around with an iPhone and a MacBook and still asking for yet another computer to carry around. Don't get me wrong-- if anyone can find a hidden niche for beautiful, usable products, Apple can, but I just don't see where an iTablet would fit in the hierarchy.
Now, the last time I speculated on Apple releases (I said we wouldn't see new MacBooks for a while), Apple decided to release MacBook updates just hours later, so for everyone out there hoping to see a new Apple Tablet, try this on: my guess is that Apple won't release an iTablet in January. Now, when I'm dead wrong (as usual), I'll just be able to claim that I predicted the opposite of what I thought so we'd get the product we wanted.
