The CDMA version of Palm's Treo 650 smartphone for Verizon Wireless combines the capabilities of a dual-band (800/1900 MHz) CDMA mobile phone with the advanced e-mail, messaging, and Web-access functions of a full-blown wireless PDA.
The vibrant, touch-sensitive 320 x 320-pixel display can show off some 65,000 colors. The Treo is ergonomically pleasing, with its buttons and controls in all the right places. Moreover, the smartphone's five-way navigator control is simply great when it comes to facilitating one-handed operations while on the fly.
Features
Measuring 4.4 x 2.3 x 0.9 inches and tipping the scales at 6.3 ounces, the Treo 650 features a 312-MHz Intel  PXA270 processor, a scant 23 MB of available storage memory, and an expansion slot for accepting add-on devices.
Rounding out the features are a built-in Qwerty-style keyboard, a VGA camera, and an MP3 player. The Treo 650's camera fails to measure up to the 1.2 to 2-megapixel image resolutions that many competing smartphones now offer.
For wireless connectivity , the phone supports Bluetooth and infrared but the lack of integrated Wi-Fi is glaring. Also, the device's onboard support for Bluetooth profiles is limited and does not support Bluetooth dial-up networking .
Powered by the Palm 5.4 operating system , the Treo 650 sports the requisite calendar, contact list, to-do list, and memo-pad functions to help you organize your life. In addition to Palm's VersaMail, Verizon offers its always-on e-mail application, Intellisync Wireless Sync, which supports POP/IMAP, Microsoft Exchange, and Lotus Notes.
Performance
While the phone supports the speedy 1XRTT network with download speeds that range between 60 and 80 Kbps, the Treo 650 does not support Verizon's hyper-fast high-speed data network, EVDO, which is capable of downloading data at speeds in the 300 to 500 Kbps range. The extra speed would have made up some for the lack of integrated Wi-Fi.
As a telephone, voice quality was no better than average and that includes the performance of the built-in speakerphone. The audio produced by the Treo handset's MP3 player is on par with what other products in its class typically deliver. (continued...)
