With promises of multi-day battery life and always-connected laptops, Windows 10 on ARM has already got us pretty excited, and now hackers have shown off the versatility of the new version of Windows by successfully running it on an old Lumia 950 smartphone.

As the name suggests, Windows 10 on ARM has been designed to bring Windows 10 to laptops and tablets running on an ARM processor. These processors are often found in smartphones, and due to their power-efficient design, it will allow laptops to enjoy many of the benefits smartphones do, such as long (compared to standard laptops) battery lives, ‘instant on’ startup speeds and the ability to use mobile internet, so you’re rarely without a data connection.
