Tha sad truth is that small screens don't work anymore, because apps are all tailored for bigger screens. I noticed this when I had an iPhone mini. It just did not work right. The UIs that are supposed to be surrounding the main part just cover too much. The range is from mildly annoying to completely blocked.
Really sad, because the device was physically very practical, and I don't really need such a big screen, just smart UIs like we used to have, that don't cram the screen full of every feature of every PM that ever worked at the company.
