Apple has unveiled a new foldable iPhone called the iPhone Duo. This device features a "remarkable hinge" and opens like a book to reveal a large 7.6-inch screen. It can be used in both folded and unfolded states, offering versatility with split-screen or full-screen modes. The seamless open screen is noted as an impressive engineering accomplishment. However, the reviewer questions its potential to change many lives, especially given its high price point comparable to a MacBook Pro. The article argues that for many, a phone is their primary computer, making a more expensive iPhone justifiable. The real oddity highlighted is that it has taken Apple twenty years to introduce an iPhone at this price range. Foldable smartphones have been available since Samsung's introduction of the category in 2019, but they have not yet gained widespread popularity. The iPhone Duo is consequently described as feeling like a disappointment, especially when compared to Apple's past "one more thing" announcements. The author contends that a completely new iPhone form factor should qualify as a significant unveiling.
