The Treo 650 looks like a great phone/PDA combo. Various reviewers seem quite impressed with the bundled software and its ease of use. Nice to see another A-GPS enabled phone on the market, too:
The GSM Treo has a quad band wireless radio that uses the 850/900/1800/1900 MHz frequencies. The CDMA model uses a digital dual-band CDMA/1xRTT radio operating on the 800/1900 MHz bands. The GSM model also support high speed EDGE networks with data speeds averaging up to 135 kilobits per second (kbps). It also features E911 compliance with a built in GPS chip that is solely used for the enhanced E911 emergency location service.
One issue seems to be the availability of WiFi drivers, which is a disappointment. According to the article, prices start at USD$449, and range up to USD$699 for the unlocked GSM model.
