The Palm Treo 680 is a combination hybrid PDA/cellphone, or smartphone as the successor to the company's Treo 650.

It was the first-ever Palm OS Treo with no external antenna.

The Treo 680 is older, larger, and heavier than the Palm Centro. But the Treo 680 has a larger keyboard which is more comfortable to type on. There are other differences between the Treo 680 and the Centro. An article on the Treonauts weblog includes a good comparison chart and some in-depth commentary.^[1]
