If each module was embedded with an NFC-like comm chip to communicate between modules, it would truly be a revolution. I would most definitely install the RF transceiver module inside my shoe and way away from my brain. The days I don't need an oximeter; I will remove it from my pocket protector. Another module would reside in my wallet for transactions at Starbucks. The speaker modules would be embeded behind my ears.
