The iPhone Duo manages to balance some compromises with unique features that make it a much better option than the iPhone Air. Here’s what you don’t get in the folding iPhone, and what offsets those losses.

iPhone Duo managed to pull off an ultra-thin foldable design without too many compromises
The iPhone Air created a fork in Apple’s lineup that gave users a premium choice that wasn’t “pro.” However, some users complained that it may have cut too many corners to achieve its thin and light design.
For the past year, the conversation around iPhone Air has been primarily about what it lacked. While I believe the iPhone Air is a perfectly fine iPhone, I think the iPhone Duo did a much better job addressing user needs.
