There's a rumor that has been doing the rounds suggesting that a 13-inch 'iPad Maxi' could be on the cards for 2014. While we're pretty skeptical over any accuracy at all on this one, it does raise an interesting question. Should there ever be a larger than 9.7-inch iPad, would you want to pick one up?
There's an obvious, if niche, market for a larger display iPad. Folks with a design-centric profession for example could be appreciative of a larger display, as could medical professionals, or even schools. More room to view, more room to do, and still retain an air of portability over something like a MacBook.
