A 4” iPhone 6C would be an interesting prospect, as it brings back memories of the iPhone 4C with its plastic back and all. After all, with smartphones having at least a 5” display in this day and age, to see a 4” model roll out might take some getting used to for your eyes. Of course, a 4” display is a whole lot easier to navigate using a single hand without stretching your fingers too much, but should Apple be able to pull off the 4” iPhone 6C release successfully, then a shift to smaller screen sizes on smartphones might just happen.
As for the next generation Apple Watch, virtually nothing official is known about it. Some whispers do mention the presence of a Facetime camera, whereas there are others which have mentioned about the possibility of Wi-Fi connectivity in addition to extra health sensors and sleep tracking ability. Hopefully the new Apple Watch won’t burn its wearer’s wrist!
