Palm today introduced a pretty sweet entry-level Treo aimed at the average Joe. The Treo 680 ($TBA) is a GSM/GPRS/EDGE quad-band smartphone offering all of the functionality you're familiar with — email, web browsing, messaging, multimedia, calendar, contacts and more. Available in red, orange, white and silver, the Treo 680 runs the Palm OS and has an internal antenna and a slimmer form factor than its Treo predecessors. It sports a full QWERTY keyboard, a 320x320 color screen, Bluetooth 1.2, and includes 64MB of user-available storage (expandable up to 2GB). If Palm ends up pricing this thing right, they may just have a big hit on their hands.
