Haha, lovely idea, I wish it were true! Unfortunately I really don't think it is. I'm pretty sure I've seen that 'tablet' elsewhere as an artist's impression. And how likely is it that a company specialising in educational tours would have prior knowledge of a device like this, given Apple's obsessive secrecy about new products? And then leak it in a graphic on the iTunes store?
I'm not buying. But I would really like to be wrong.
