Qualcomm (QCOM) appears to be the big winner on the Nexus. We've found at least three of their chips in here already.
On the left is a RTR6285 RF transceiver.
The large chip on the right is the nexus of the Nexus. It's a Qualcom (QCOM) QSD8250 "Snapdragon" 1 GHz ARM processor.
The small chip between the two Qualcomm (QCOM) chips is an Audience A1026 voice processor, including ambient noise cancellation.
