What is not said is the weight of the beast. If it is heavier than 2lb, no one can use it as a tablet. But if it stay below 1.5lb (Ipad 2 weight about 1.5lb) with bigger screen and higher resolution, I can see a lot of application. It is a niche market and is not intended to replace IPad air or Ipad mini. I would jump on one if the weight is in check as I need the bigger fonts. And in Asia, writing is a good way to do data entry and bigger tablet is attractive as well.. If they can make a big tablet with the same weight as the current IPAD air, I think they have a big winner. The innovation is going to be under the hood in the weight reduction, higher resolution, multitasking, and productivity software.
