Edward C. Baig wrote a terrific review of the palmOne Treo 650, urging his readers to "trade in your dumb phone for a smart one." He liked the improved keyboard, display, removable battery, and Bluetooth. Baig was most concerned with the lack of WiFi, the rather weak digital camera, and the price. No surprise there.

I always scratch my head when I read that a reviewer thinks that a multi-function device like the Treo 650 should have mobile phone data service, Bluetooth, and WiFi. Having all three technologies in one device makes me worry about supportability from the carrier's perspective. As long as we continue to accept carrier subsidies on our handsets, the complexity of handsets will be a major factor in whether we are able to buy them and if so, how quickly.

Amazon.com's best deal on the Treo 650 at the time of this writing is $369.99, if you sign up for the right contract with Sprint PCS.
