Microsoft recently launched a new Surface Go tablet with two different initial configurations for the affordable slate, and now it looks like a third variant is also available, but apparently only through Costco in the US at the moment.

The base model of the Surface Go (pitched at $399.99, £379.99 or AU$599.99) has 4GB of RAM and 64GB of eMMC storage, whereas the more expensive model ($549.99, £509.99 or AU$839.99) runs with 8GB of RAM and a 128GB SSD.
