(Pocket-lint) - Samsung has taken the wraps off two new tablets at Mobile World Congress: the Galaxy Tab S3 and this, the Galaxy Book, which is fully set on replacing your laptop.

It's offered in two sizes; 10.6in and 12in, the latter delivering more premium specs and comes supplied with a detachable keyboard so you can easily switch between laptop and tablet modes. Samsung envisages professionals using the Galaxy Book not only as a main computer at home, but on-the-go as well. 

The 10.6in model has a full HD TFT display, a 2.6GHz, 7th Gen Intel Core m3 processor coupled with 4GB of RAM and 64GB and 128GB storage options. Both can be expanded up to 256GB via microSD card. The built-in 30.4W rechargeable battery claims to last for up to 10 hours depending on usage, and like the Tab S3, can be used with an S Pen stylus.

The 12in version of the Galaxy Book meanwhile has a 2160 x 1440 Super AMOLED display and a 3.1GHz 7th Gen Intel Core i5 processor with either 4GB of RAM and a 128GB SSD, or 8GB of RAM and 256GB SSD, making it more than capable of becoming a laptop replacement. You also get a 39W battery which promises to be good for up to 10.5 hours.

The 12in Galaxy Book as a 13MP rear-facing camera with autofocus and a 5MP one on the front, while the 10.6in makes do with just a 5MP front-facing camera and both support USB Type C, but the 12in gets two ports compared to the 10.6in's one. Samsung's proprietary software S Pen software functions, including Air Command, Samsung Notes and Samsung Flow are supported across both models.

A price and release date for the Galaxy Book is still to be confirmed.
