Well, I have talked to some of the Intel guys at Maker Faire Rome, and there are in fact two different versions, the EDI1.LP* SKUs that correspond to the Wearable description is a low power version, not the CPU, but the wireless radio has been limited to keep the thermal properties at a lower level.
For development and general tinkering, they suggested to use the regular one (EDI1.SP*) and if you are concerned about the device heating up, run the radio in bursts and keep a low duty cycle.
It's also the standard one that is bundled with the two breakout boards.
