Microsoft is planning to unveil new Surface devices later this month. Sources familiar with Microsoft’s plans tell The Verge that the company will unveil Surface Pro 10 and Surface Laptop 6 hardware, aimed at business and commercial customers, on March 21st.

The March event will be focused on minor spec bumps to the Surface Pro 10 and Surface Laptop 6 commercial models, but a larger redesign is planned for the consumer models of both devices this spring. While the commercial Surface Pro 10 will sport the latest Intel chips and a familiar design, Microsoft is moving to an OLED display on the Surface Pro 10 for consumers.

Windows Central first reported details of an OLED Surface Pro 10, claiming Microsoft would unveil the new OLED model later this month. Microsoft will not be unveiling this device on March 21st, we’re told. The March event is focused on minor commercial refreshes of existing Surface models instead.

Both the consumer Surface Pro 10 and Surface Laptop 6 models will ship with Arm processor options, allowing Microsoft to update the designs of both devices. Windows Central reports that the Surface Laptop 6 “will feature a more notable design update” thanks to thinner display bezels, rounded corners, a haptic touchpad, and two USB-C and one USB-A ports.

The Surface Pro 10 OLED model is said to include a new ultrawide front-facing webcam, a built-in NFC reader, and an anti-reflective OLED display that supports HDR content. Microsoft will reportedly ship the Intel variants of the Surface Pro 10 and Surface Laptop 6 in April, followed by the Arm variants in June.

Both the commercial and consumer versions of the Surface Pro 10 and Surface Laptop 6 will feature Microsoft’s latest Copilot key, part of a broader AI effort for Windows. Microsoft has not yet detailed its big plans for AI-powered features in a Windows 11 update due this year, but the company is likely to do so at its upcoming Build developer conference.

Microsoft is working to improve its Copilot experience more broadly in Windows 11, but it’s also working on a new AI Explorer experience, according to Windows Central. Described as an “advanced Copilot,” it sounds like a feature that will catalog everything you do on your PC so you can search for moments in a timeline or using natural language. Microsoft used to ship a Timeline feature in Windows 10 which tried to achieve the same, but this time it’s AI-powered and will work across any app.
