I don't disagree with Gruber so much as he wears me out. As usual he can't resist overstating his case. If he was looking for an analogy, he might have considered the many other times Apple has added by subtraction (floppy disc, optical drive, serial ports). Each time resulted in much wailing and moaning that was quickly forgotten, until the next time. The situation is little different with the iPhone X. Apple hasn't broken from the past in a radical way so much as made a few incremental changes. They may disorient or even annoy longtime users for awhile, but they aren't half as important as Gruber makes them out.
