Overview

The name of Apple's first foldable is giving some people déjà vu.
While you might not think the word "Duo" as part of the moniker would be controversial in any way, many people point out that it's the name Microsoft used with its Surface Duo foldable products.
Way back in 1992, Apple introduced a device called the Apple PowerBook Duo.
The Microsoft Surface Duo launched in 2020, the same year Apple introduced the MagSafe Duo Charger.
Some reviewers felt the Surface Duo 2 excelled at multitasking with split screen views, and this is something Apple does well with the iPhone Duo, too, based on early hands-on experiences.

The article, shortened and in plain language

The name of Apple's first foldable is giving some people déjà vu.

While the device isn't groundbreaking it marks a shift for Apple.

While you might not think the word "Duo" as part of the moniker would be controversial in any way, many people point out that it's the name Microsoft used with its Surface Duo foldable products. (There's also language app Duolingo and the Google Duo VoIP service that eventually folded into Google Meet, but those are stories for another day.). Because of this comparison, the internet has been roasting Apple.

Way back in 1992, Apple introduced a device called the Apple PowerBook Duo. The laptop-style computer wasn't just a passing fad, it was produced through 1997.

Further, when you explore Apple's trademarks, while the company now owns the trademark for iPhone Duo, its trademark list also interestingly includes MagSafe Duo Charger.

The Microsoft Surface Duo launched in 2020, the same year Apple introduced the MagSafe Duo Charger.

Its Android 11 with Duo 2 software was unreliable, it did not have an outer screen, and the camera app was not good. Some reviewers felt the Surface Duo 2 excelled at multitasking with split screen views, and this is something Apple does well with the iPhone Duo, too, based on early hands-on experiences.

Microsoft ended the Surface Duo 3 in 2023, and had plans for another foldable that never materialized. Plus, Apple itself had already used the Duo name anyway. IPhone Duo might not be the first Duo foldable, but it will likely be much better received than the older one.
