After stubbornly resisting for years, Apple has finally joined the big-screen smartphone movement with its two latest models, the iPhone 6 and iPhone 6 Plus, which go on sale Friday. But it hasn’t just expanded the screens. It has radically redesigned the iPhone, making it thinner and more curved, and has beefed up everything from the screen to the performance to the battery life and wireless speed. I’ve been testing the more mainstream of the two models, the 4.7-inch iPhone 6, for about a week now, and I think it’s a terrific phone. In my view, it’s the best smartphone on the market, when you combine its hardware, all-new operating system, and the Apple ecosystem whose doors it opens. That includes a new service called Apple Pay for buying goods in stores and online electronically via the phone; it’s due next month. Apple Pay will only work with these latest iPhones, and Apple’s forthcoming smartwatch. But this review is just part of the story. While I’ve been testing the iPhone 6, my three colleagues on Re/code’s reviews team have been testing the rest of Apple’s new iPhone and iPhone-related products. Lauren Goode has the lowdown on Apple’s first phablet, the 5.5-inch iPhone 6 Plus, here. Katie Boehret reviews the new operating system, iOS 8, here. And Bonnie Cha’s take on the iPhone’s all-new onscreen keyboard, and its third-party competitors, is here.
