Just read news over PalmInfocenter:
Rumor: CrunchGear is reporting a rumor this morning that makes the claim that the Treo 680 has been delayed due to a manufacturing error. Their reliable source states:

Apparently 144,000 Treo 680s were shipped out and had to be sent back because some genius forgot to connect the internal microphones.

The Treo 680 is being produced by Inventec. The 680 is the first device they have been contracted to manufacture for Palm.

Hum……..Thats a good mistake, that is just clever!
Wonder who did the QC/QA? I think he/she deserve to get a BIG thumb up AFTER recieving His/Her big envelope.
