Minoura new powermeter

Minoura announced a new cycling computer. It's pretty cool because it's the first computer of e-paper. So that's great.

But what do I see in the functionlist?

FLEX features the following 18 functions even on the basic model;
Wattage: Current / Maximum / Average / Pace Arrow

How does this new device measures power? Like polar? Or like the ibike? Or?

Price: 150 dollar
