Sometimes it really is the details that matter.

Or, in the case of cool new hardware, it's the software that can make or break the experience. Apple forcefully made both points with the launch of its new foldable smartphone, the highly anticipated iPhone Duo, which is expected to ship on October 23 at a starting price of $1,999.

The Duo features a very nice, if arguably derivative, hardware design that at first glance looks similar to other recent passport-style phones, such as Samsung's Z Fold 8. But the phone distinguishes itself with a new version of iOS and multiple applications that have been clearly and cleanly optimized for the foldable form factor.

It's these software refinements that make the iPhone Duo stand out among other foldable competitors. In fact, even with very limited hands-on time with the phone, I'd argue that Apple has redefined the foldable category and experience with the launch of the Duo. From simple adjustments, like moving app icons from the bottom of the screen to the side, to more elaborate touches, such as the visual transition from the front display to the larger inner screen, Apple has created a range of enhancements that make foldables feel brand new.

Given that Samsung first introduced the world to foldable phones back in 2019, that's quite an accomplishment. As a vocal and avid supporter of the category since those early days, I've used every single foldable Samsung has created as my daily driver, so I was very curious to see if Apple could use its very delayed entrance into the category to its advantage.

Clearly, it has.

Admittedly, some of the capabilities Apple showed off on the Duo are similar to features we've seen from companies like Samsung, Motorola, and Google over the years. However, the level of refinement and the collective experience Apple demonstrated at the launch event showed how thoroughly the company has thought through the details to create a true foldable experience, rather than simply putting the same software into a different physical package.

I expect the iPhone Ultra will end up becoming the hot new tech status symbol in the near term.

Speaking of hardware, on closer inspection the iPhone Duo does have some important differences compared with other foldable designs. Compared with Samsung's Z Fold 8, for example, the Duo is slightly shorter and wider, both when folded and unfolded, giving it a form factor that's a bit easier to hold. However, the Z Fold 8 is a noticeable 1.87 ounces lighter and about 0.7mm thinner, likely reflecting the many years of experience Samsung has had refining and shrinking its foldable designs.

The hinge designs are different as well, which could partially explain the weight difference, with Apple's design feeling a bit firmer, though the distinction is relatively subtle. The iPhone Duo also has a more robust IP68 water and dust resistance rating versus the Z Fold 8's IP48.

In addition to the iPhone Duo's slightly higher-resolution displays, the biggest difference is that, thanks to a new nano-texture finish layer on top of the screen, there's virtually no visible crease. As a very long-time user of foldable phones, I can say with certainty that creases on most modern foldables aren't really noticeable when you're actually using the device. However, for first-time users considering a move to a foldable, it's an important issue to address.

One of the biggest surprises with the iPhone Duo is the price. It starts at $1,999 for a 256GB configuration, which is $100 more than the similarly configured Z Fold 8. Early rumors suggested pricing would begin well above $2,000.

By staying below the psychological $2,000 barrier, Apple managed to keep the Duo within reasonable consideration for people who are now accustomed to paying around $1,500 for well-configured "regular" iPhone Pro and Pro Max models. Of course, at the high end, a 2TB configuration of the iPhone Duo is expected to hit an eye-watering $3,199.

Despite the better-than-expected pricing for the base configuration, the iPhone Duo and foldables in general clearly aren't for everyone. Right now, the category makes up only about 2% of the total smartphone market, although it is one of the few sub-segments that continues to grow.

My expectation is that the introduction of the iPhone Duo will raise interest in the entire category and could eventually help push foldables closer to 10% of the market over the next few years. Apple will undoubtedly be the primary beneficiary of that growth, but companies like Samsung, Motorola, and Google will likely benefit as well.

In the meantime, I expect the iPhone Duo will become the hot new tech status symbol. Initial manufacturing volumes are rumored to be low, and combined with the higher price point, that means it's likely going to be difficult to get one.

Eventually, that will pass, but along the way, I'm hoping a much wider audience will be exposed to the benefits that I think foldables bring to the smartphone category. Combining a large screen with a pocketable form factor is something that, once you've gotten used to it, is very hard to give up.
