(NEW YORK) — The Microsoft Surface Duo hits shelves this month, marking the company’s long-awaited return to the smartphone market.

The $1399 Duo is a “foldable” phone- a category that also includes Samsung’s $1999 Galaxy Z Fold2, and Motorola’s $1399 Razr 5G. Where those devices feature a single, ultra-thin bendable screen, the Duo instead has two screens connected by a hinge mechanism.

“Two screens side-by-side is what this product is about,” says Microsoft Chief Product Officer Panos Panay in an interview with ABC Audio.

Digital Trends Editor In Chief Jeremy Kaplan says having two screens allows users to compartmentalize data more easily.

“What Microsoft’s engineers have leaned into is cognitive science. And they’ve shown that, by separating this thing, by actually having two physical screens, your brain is better able to process information.”

But having a dual-screen device comes with drawbacks, which have been noted in early reviews of the Duo.

“There is a learning curve that comes with it,” says Panay. “You can see that in the reviews, you can feel it in the conversations.”

He adds it may take awhile to warm up to the device’s new form factor.

“I don’t think you’ll end up in a frustration point. It’s just a matter of finding all the things you can do with the device takes time.”

Other complaints from reviewers centered on the Duo’s camera setup. The Duo features a single, 11-megapixel camera sensor. Samsung’s recently unveiled foldable, the Galaxy Z Fold 2, boasts five cameras – three of which are 12-megapixel units.

“We get asked all the time: why didn’t you put a better camera on the back of the device? But ultimately it wasn’t designed for that,” says Panay.

The Duo also garnered attention for its software. Existing Windows phones used Microsoft’s internally designed operating system. The Duo uses Google’s “Android” software. Panay says the reason Microsoft opted to borrow another tech giant’s software came down to the predominance of Google’s apps.

“Android is so powerful for this product. You know, the millions of apps that you can choose – the ones that are most important to you.”

It’s a sentiment Microsoft CEO Satya Nadella echoed in an interview with ABC Audio last year, after the partnership with Google was first announced.

“We felt that there was a real need for someone to come out and innovate on this next inflection point around dual-screen devices, and we said- let’s use Android.”

Kaplan thinks Microsoft is making a wise decision by partnering with Google.

“It makes sense to lean into Android here. Microsoft has said, ‘we want to be where our customers are, we want to be where people are.’ And where are people? They’re on the Google Play Store. They’re using Android phones.”

As for the future of folding smartphones, Panay says he’s optimistic.

“I think it’s the form factor where phones or phones should be going,” says Panay.
