This is exactly what I wanted: a series of decent pictures comparing the 4-, 4.7- and 5.4-inch sizes from different angles. Well done, iZac!
According to the ruler, the new size is a little too close to the iPhone 7, a little too far from the SE. Our new hero does make a good point, however:
From handling it I can say it does feel like a bit more of a stretch than the SE, which just nestles very comfortably in my hand. BUT, although it’s nearer to the 7, I will note that it feels a lot more manageable because the square profile and flat side lets you actually grip the device.
Overall, I think I can get used to it and finally retire my stalwart SE.
