As expected, Apple has once again chosen to try and appeal to the widest audience possible by introducing the 6s range with the same 4.7-inch and 5.5-inch offerings that were brought to market with last year's iPhone 6. Additionally, following on from the precedent set last year, this latest generational iPhone release once again sees the two devices separated by rather marginal technical differences. The decision on which device to buy will really only come down to one major deciding factor; do you want to go as big as possible at 5.5-inches or keep it at 4.7-inches?
