I hope you weren't looking to get your hands on the Treo 680 anytime soon since it's looks like a manufacturing gaffe has delayed shipment for a little while. Apparently, some Einstein forgot to connect the internal microphone, or, as one patriotic blogger put it, it'd be like "if Ford sent out 10,000 Explorers without connecting the brakes." Some 144,000 Treo 680s were sent out that need to be returned to the factory for fixin'.
Considering they've tried shipping it already, I would imagine that we should be seeing it en masse sooner rather than later. Though I must say, not everyone is universally praising the smartphone.
