The iPhone 7 may be the best version of Apple's smartphone to date, but it's garnering lukewarm reactions from reviewers and pundits. The practical improvements in the new iPhone are praiseworthy, but they come at a cost. "Waterproofing and better battery life have been common iPhone feature requests for years, and the camera and speed improvements are nothing to sneeze at," wrote reviewer Andrew Cunningham, "but you'll need to buy into Apple's vision of the future if you want to get them." That vision includes a world without buttons or wires.
