So I was thinking there a lot of size choices for iPad all of a sudden. What line would Apple chiise to drop if they only wanted to continue to support 3 sizes. I think the mini has a place for its extreme portability. The 12.9 is a great size for those who use theres for work (as i do as a designer) and i believe it’s by far the superior device for multi-tasking (though i may be bias as a 12.9 user). So my thought is it would come down to 9.7 and 10.5 as they are so close in size. With 9.7 being the well established size i would have to go with dropping the 10.5.
