2. NFC functionality
For the first time Apple has embraced near-field communication (NFC) technology in both of the new iPhones. While other devices have arguably struggled to find a definitive use case for NFC, Apple has tightly integrated the technology with its Apple Pay service to enable contactless payments to be made with both the iPhone 6 models and Apple Watch.
Currently only available in the US, Apple Pay's NFC contactless payments will work in participating retailers, including Subway, McDonald's and the Disney Store. Other nations will have to wait and see whether the Cupertino giant decides to bring Apple Pay from across the Atlantic.
Concerns over NFC security are addressed via a Secure Element chip, which stores payment details and data on the chip rather than in a device's memory or in Apple's iCloud service.
Contactless payments aside, app and accessory developers will likely be relishing the opportunity to harness NFC technology in tandem with Apple's famously well-curated App Store. A slew of NFC enabled accessories could accompany the retail release of the iPhone 6 in September.
1. New screen sizes
For years Apple steadfastly refused to increase the screen size of its iPhones, sticking to the 3.7in size that former CEO Steve Jobs claimed was the ideal form for a smartphone.
However, others in the market clearly disagreed and rivals such as Samsung have made hay in the new 'phablet' space, at Apple's expense. Even the increase to 4in screens on the iPhone 5, 5C and 5S could not claim to offer any competition.
Now, though, Apple has forever turned its back on smaller-screen smartphones, with both new devices sporting larger displays.
The 4.7in iPhone 6 should still appeal to those who don't want an oversized phone or a mini tablet in their pocket, while the 5.5in iPhone 6 Plus is definitely a phablet.
The iPhone 6 Plus also has the ability for the home screen to dynamically switch to a landscape mode when used in this way. Apps can also display more information with multiple elements. For example, the message app can display a message thread on the right and a list of other chats on the left.
Apple may be late to the party with these large screens but for fans of the company who would never dream of moving to Android or Windows Phone, the new screen sizes will no doubt be a welcome upgrade.
