That’s because the cheapest model has 2GB of RAM and 64GB of storage, while higher-priced models have 4GB of RAM and 128GB of storage.
Now it looks like there’s another option: Microsoft is offering a model with 4GB of RAM and 64GB of storage.
As Betanews notes, it sells for about €659 in Germany, which puts it about halfway between the European prices for the entry-level and high-end models.
Like other versions of the Surface 3, this model sports a 10.8 inch, 1920 x 1080 pixel display, an Intel Atom x7-Z8700 Cherry Tail processor, 802.11ac WiFi, Bluetooth 4.0, a USB 3.0 port and Windows 8.1 software.
It has a built-in kickstand and the tablet is compatible with an optional Surface Pen and Surface Type Cover, but those accessories are sold separately.
