The Treo family album

It could be argued that the most notorious family in the smart-phone community is the Treo family. The Palm Treo 650 has reigned as the godfather of these cell phone/PDA devices, thanks to its winning combination of a sleek form factor and a solid feature set. With its built-in QWERTY keyboard, its sharp screen, and its productivity tools, it's an offer that mobile professionals can't refuse--and one that the carriers can't either, as Cingular, Verizon Wireless, and Sprint all carry the phone. Late last year, Palm also shook up the smart-phone world by making a deal with the enemy: Microsoft. However, in the end, the Treo 700w made good business sense, successfully marrying Palm's hardware with the Windows Mobile operating system. And now, the latest addition--the Treo 700p--updates the Palm OS side of the family and is one well-connected device, with EV-DO support and dial-up networking capabilities. Read on to meet the whole family and see if one is right for you.
