Late last year in October, Microsoft had announced the Surface Duo, the company’s first ever Android device and first-party smartphone (if you can call it that) release in years. What makes the Surface Duo special is its symmetric dual-screen nature and 360° hinge mechanism that allows the device to fold itself shut like a book – to fully opening itself up with two opposing displays. Today Microsoft is finally making the Surface Duo available for pre-order – although availability will be limited to the US.

Starting off with the uninteresting stuff – the internal hardware of the Surface Duo isn’t all that exciting as it features a last generation Snapdragon 855 SoC. Given the device’s early announcement last year it seems Microsoft took a long time to bring the device to market. We’re seeing a standard amount of DRAM and storage space with 6GB and either 128GB or 256GB options. All in all there’s nothing too special about the internals here and are in line with 2019 flagships.

The device’s key characteristic is naturally its symmetrical folding design with two 5.6” 1800 x 1350 resolution OLED screens. Although we call this a folding device, this doesn’t actually apply to the displays as they’re two distinct units covered with solid glass.

Further unique to the design is the hinge mechanism which is symmetrical as well – it allows for a full 360° tilt of the two sides, meaning you can have the device either fully shut, or you can have it fully opened with both screen facing outwards.

Microsoft opted for relatively unusual form-factors here as the screens are each 4:3 – and when opened up it gives you a sort of effective 8.1” diagonal 3:2 surface to work with.

The dimensions of the device come at 145.2mm height in portrait mode, and one side is 93.3mm wide, which opens up till 186.9mm. Each half is extremely thin at only 4.8mm meaning that even when folded it remains a relatively reasonable 9.9mm in thickness.

The device’s 360° folding nature means that the internal screen surface can face completely outwards, and Microsoft took advantage of this for their camera design, of which the Surface Duo only has a single unit. The 11MP 1µm pixel f/2.0 standard wide-angle unit is relatively conservative in specifications, but that’s the compromise that had to be made to fit into a 4.8mm thick chassis and not having the possibility to employ a camera bump.

Microsoft positions the Surface Duo as a productivity device, and its first-party applications such as the Microsoft 365 suite will be optimised for the experience. This seemingly will be the deciding factor as to how the Surface Duo will be received, as it represents quite a niche device market.

The Surface Duo is available for pre-order now at a very high price of $1399, with availability only in the US and compatibility with AT&T, T-Mobile and Verizon, with availability starting September 10th.

The device’s high price and relatively lacklustre specifications will likely result in limited adoption amongst users- and the device in general feels more like an experiment than a product that’s aimed at commercial success.

    You've got to let it go. No, it's not hard to make a phone app, it's hard to make a million phone apps.

    For $1399 it needs a Snapdragon 865 + 8GB of ram and Wifi AX battery also needs to be 4000+maH minimum. With how its currently configured I would pay $1000 for it. And 50 grams lighter wouldn't hurt :)

    Big batteries and lightness dont go together.

    The $250 moto g power has a 5000 mah battery. There is no reasn the Duo should have one smaller then the moto with such a large body to work with.

    Large but very thin body. I don't know if the batteries are split in two, one beneath each screen, or if one side has all the cells. They could have made a slightly thicker device with a huge 5000 or 6000 mAh battery pack.

    Not sure what Microsoft is thinking here. Either this bombs terribly as a productivity device and Microsoft loses both face and money, or it works and people start to take Chrome Book seriously and move away from Windows.

    People do take Chromebooks seriously, much to the dismay of cybersecurity folks and data privacy advocates that understand what Google is doing behind their backs.

    So we have 5-6000 mAh batteries in smaller devices and ms thought puting only 3500 mAh in these?
  • mkozakewich - Wednesday, August 12, 2020 - link

    I've seen a dual-battery device run at 6.4V at less mAh, so it looked bad on paper, but it actually had twice the watt-hours, so I'd like to make sure on that point before making a decision. If it's only 13 Wh, that's not a lot.

    Then again, the entire Surface Book display (or "clipboard") has only 19 Wh, so maybe that's what they're used to putting into a device of this thinness.

    $1400 brick. Only sheep and fools are going to buy this trash.

    What does it have ? no 3.5mm jack, no sd card and 3500mah with SD855 processor. This garbage should be wiped from existence.

    Damn, nothing is compelling about this product. Don't waste money on this trash. Get an LG V60 which can do this with a latest processor and has a better battery, has Wacom Stylus support, has a 3.5mm jack with SD slot too and not just that it can take much better pictures and has solid pro audio and video capabilities.

    This garbage also has sealed battery for what ? to throw it in a garbage dumpster after 1 year &Just because it folds ? how about First Party Android app support for that ? None, all of them are blown up UI, Google shamelessly and recklessly abandoned Android tablet and started chasing stupid Google Chrome OS and flopped harder than anything with Pixel Slate and other trash, now they don't have proper app support for Chrome OS until 2020 with all that hooplah of the Crouton and etc garbage. Talk about zero focus. Pixel is a doomed division failing hard and Surface seems to chug along because of the Windows only.

    Panos Panay is a fool and they gave Windows development to this idiot, Windows10 looks horrendous due to it's hybrid BS of tablet and desktop UX in same without a choice. M$ ofc doesn't care as long as their Windows Enterprise customers bend over for that WaaS unstable garbage. But with Home and Pro even worse after 6 months new update with new bugs and breaking Desktop Composer too.

    And for this money one can build a brand new Ryzen beast, horrible pricing for such an inferior product in terms of both HW and Software, made by idiotic fools at MS who got into that company probably because of higher PR speak big mouth and some virtue signalling.
