Actually I think he would appreciate the beauty in using 1:1.4, the same as metric paper, to maintain the ratio.

Having watched the original iPhone event live, bringing the pencil to the iphone would make him roll over in his grave.

Would probably push the engineers to deliver three-way foldables like the Huawei Mate XT from two years ago. The two-way folding phones are wasting a screen and will go down in history as an abomination. The weird 1:1.4 width:height ratio wouldn't be necessary if you could 3x the screen size instead of only 2x. At 3x, the ratio could be 1:1.73 folded, giving you 3:1.73 unfolded (which equals 1.73:1). 1.73 is much closer to 16:9 (1.77) than 1.4 is.
