Not just developers!
By removing the SD slot, Apple have upset a great many photographers too. Only the latest DSLR cameras have wifi and in any case, photographers rely on the redundancy and portability of the SD format. Apple have made a big mistake here. See https://goo.gl/cdGKlv
Another mistake. Why didn’t they provide a SIM slot option for cellular connectivity? Apart from neglecting the utility of this. Surely this is a wasted upgrade opportunity. iPad’s have had this option from day one.
Of the touch bar. I think is quite an innovation and can imagine a future where such technology replaces the keyboard altogether. Are developers missing the point here? Doesn’t this provide an opportunity for a touch bar app which will actually improve the developer experience?
