Reviewers find much to like about the iPhone 5S (AAPL +1.5%) and 5C's hardware, and generally give a thumbs-up to iOS 7 along the way.
The NYT's David Pogue praises the performance of the 5S' A7 CPU (scored well in AnandTech benchmarks), the improved color balance yielded by its dual-LED flash, and the convenience of its fingerprint sensor. "The best part is that [the sensor] actually works — every single time, in my tests."
Pogue also praises iOS 7's revamped UI and plethora of new features (e.g. new apps, improved multitasking, iTunes Radio), while granting not everyone will love the former. "I think you should install it. The structure, layout and features represent some of Apple’s best work. The look of iOS 7 — well, that judgment is up to you."
Walt Mossberg: "If you are an iPhone fan with any model older than the iPhone 5, the new 5s will be a big step up ... There are too many new features in iOS 7 to list here, but it’s a big improvement."
In his 5S review, Engadget's Myriam Joire states Apple "took a good product and made it better through hardware upgrades, new features and a completely revamped [OS]." But he adds "a 4-inch display likely won't cut it" for "anyone who needs copious amounts of screen space."
Joire on the 5C: "We're happy with the iPhone 5C in terms of performance and battery life, but we're longing for a better camera and a larger screen ... We think most buyers will pick the iPhone 5C for the price and color choices alone, while the iPhone 5S will appeal to power users and gamers."
