At its Galaxy Note 10 Unpacked event Samsung unveiled a surprise new Galaxy product - albeit one that had been rumoured - the Galaxy Book S.

This lightweight 13in laptop is the latest to run on the Qualcomm Snapdragon 8cx chipset - the laptop-focussed processor setup from a company best known for its phone chips.

Like other Snapdragon laptops, that should bring with it two big benefits for the Galaxy Book S: always-on Gigabit LTE connectivity, and a whopping 23-hour battery life - which should be enough to handle most commutes.

Despite having the “essence of a phone” according to Samsung, the Galaxy Book S will still run Windows 10 - though like other Snapdragon laptops you should expect some compatibility issues, and it will likely default to running in the limited ‘S Mode’, which locks you into Windows Store apps.

The 13.3in HD display will double as a 10-point touchscreen, and on the inside the Book S comes with 8GB of RAM and either 256 or 512GB storage - expandable up to 1TB with a MicroSD card. It will also include AKG speakers with Dolby Atmos support, though that's no real surprise from Samsung.

At just under 1kg, and only 6.2mm thick at its thinnest point, this is a seriously lightweight device too. That brings downsides too though - it looks like there's only a headphone jack and two USB-C ports, one of which doubles for charging duty, though Samsung has squeezed a fingerprint sensor and webcam into the body too. The curved rear hinge also borrows from Asus, though has a more natural flow to its design.

Alongside the new laptop Samsung also announced three versions of the new Note 10 - including a Plus model and 5G variant - along with further details on the already-announced Galaxy Tab S6 and Galaxy Watch Active 2.

The Galaxy Book S will launch in two colours - Earthy Gold and Mercury Gray - some time in September, with prices starting from $999. Previous Samsung laptops haven’t launched in the UK, and we’re not sure yet if the Book S will follow suit.
