True, they should have never made an iPhone with a screen more than 4”, never released the iPad mini, and never shipped a stylus for the iPad because those are all things Steve said were bad.
Did you notice how it's you who's reducing it to "What Jobs said" strawman to avoid addressing the actual arguments?
As far as I can tell your only argument against adding a touchscreen is that Apple has previously taken the stance that they would not do it, so that I what I was responding to.
But of course yes, Apple has vaguely and generally declined and their products are flops. Unlike the good old days of the first versions of Mac OSX, the G4 Cube, the iPod HiFi, the flaking-paint Titanium Powerbook, the bendy iPhone 6, or of course Ping, the revolutionary music social network.
