20 Guesses: What Rumored Apple Tablet Might Look Like (PHOTOS)

Apple is working on a tablet computer that could be announced early next year.

Apple chief Steve Jobs has been "pouring almost all of his attention" into the device, the WSJ reported earlier this year.

What will it look like?

That's one of the great unanswered questions in technology right now: Only a select group of designers, engineers, and executives at Apple and its partners know for sure. (And depending if and when it's released, many things could still change between now and then.)

In the meantime, many gadget enthusiasts and illustrators have published concept sketches of what they think the Apple tablet could look like. Not surprisingly, many of the concept design cues come from Apple's existing gadget lines: The iPhone and Mac.
