Well, Diablo was still designed for 4" stylus screens, for a constrained mobile device. So that means one application on screen at the time, one view at a time. Those are pretty bad limitations for a 10" lapt... Booklet. Application UI's were designed with these constraints in mind, so blowing them to 10" would in most cases just break and not look very nice. Of course nothing is impossible, given enough time, motivation and resources.
