The Treo 680 is here, available now with a contract from Cingular for $200 or, unlocked from Palm, for $400. As a Treo 650 user myself, the two most interesting features for me: Internal antenna, and, most intriguingly, the ability to decline calls with a text message, which sounds ever so much friendlier than just hitting the "REJECT!" button and sending the caller to Voicemail Hell.
