Total key count: 42 keys.

The interesting thing about the Atreus is that it doesn't have the top row of number keys. And, it doesn't have the key columns on the sides neither. (that's normally for {Tab, Shift, Ctrl, `, Return, ⌫ Backspace, …} keys).

The Atreus minimize key count extremely, with a total of only 42 keys. To access number and symbols such as {! @ # $}, you need to press a combination with a modifier key. Its large thumb keys are not right under the thumbs.

Because only 42 keys, you'll have problems typing Chinese, Japanese, Russian with it. because you need to switch layers every 3 or so key strokes.
