iPhone Duo reviews mixed as Apple's foldable hits stores

Apple's first foldable phone, the iPhone Duo, hit stores worldwide Friday at about $2,000, receiving mixed early reviews that praised its design but questioned its value for typical users. Reviewers lauded the Duo's sturdy, barely visible hinge and overall build, but noted compromises like a missing telephoto lens and unoptimized third-party apps. Several prominent critics, including John Gruber, called it a polished prototype rather than a finished product, recommending against it for many customers. Tech commentator Marques Brownlee said it's likely a "no" for those who mainly text and browse, though fun for enthusiasts. Conversely, Berlin creator Patrick Wolter praised it as a phone and iPad replacement, suggesting it could eventually replace his other devices.
