Just wanted to know your opinion on that.
Is anybody concern of the high level of SAR for Atrix?

From the legal guide:
"The highest SAR value for this mobile device when tested for use at the ear is 1.47 W/kg, and when worn on the body, as described in this guide, is 1.35 W/kg. The SAR value for this mobile device in its data transmission mode (body-worn use) is 1.35 W/kg."

This is pretty high (the FCC's limit is 1.6 W/kg).

And how come the Samsung Infuse has SAR 0.20 W/Kg?
