TOKYO -- At first glance, Apple's new iPhone 8 series bears a strong resemblance to the American tech giant's earlier smartphones. But taking the cover off reveals some noteworthy tweaks and new technologies.
Both the iPhone 8, with its 4.7-inch display, and the 5.5-inch iPhone 8 Plus cut a sleeker figure than their last-generation counterparts, sporting a case covered front and back in reinforced glass that melts seamlessly into a smooth, rounded edge. The iPhone 8's stainless steel frame costs less than half the previous model's $40-or-so aluminum alloy frame, even with the cost of the glass included. The larger model uses the same frame as its predecessor.
