The 6.05-oz Treo 650 smartphone from PalmOne combines the capabilities of an all-digital cellular phone with the e-mail, messaging and Web access capabilities of a full-blown PDA.
Even better, the Treo 650 is up and running on Sprint's dual-band CDMA network  , which features high-speed data capabilities.
Powered by the Palm operating system , the Treo 650 can deliver up to 5 hours of continuous talk time off a single battery charge. Moreover, batteries can be swapped while on the go to keep the handset up and running with nary a hiccup.
Building on the success of the Treo 600, PalmOne has added Bluetooth technology to the mix to enable end-users to wirelessly link their handsets to Bluetooth compatible headsets, car kits, computers and printers. The PalmOne engineers also have added full access to Microsoft Outlook Exchange, in addition to POP3 and IMAP4 e-mail clients.
Moreover, the Treo 650 now includes an embedded global positioning system (GPS) chip for enabling the handset to take advantage of E911 emergency location services as they become available.
Under the Hood
Measuring 4.4 x 2.3 x 0.9 inches and weighing in at 6.3 ounces, the Treo 650 appears to be identical to its predecessor, at least on the outside. But under the hood, the device has been optimized to handle multimedia through the addition of a 312-MHz Intel PXA270 XScale processor .
The Treo 650 smartphone also incorporates a vastly improved TFT display, a VGA camera with an MPEG-4 video-capture capability, plus 32 MB of RAM. In addition to 22 MB of available non-volatile memory, the Treo 650 includes 10 MB of true RAM on which Treo applications are copied before they run.
The handset's display measures 2.5 inches diagonally and beats the Treo 600 by supporting 65,000 colors with a 320 x 320 resolution. The new smartphone also incorporates an expansion slot that accepts industry-standard SD memory cards and SDIO peripheral cards. In addition, the new Treo 650 sports a more responsive Qwerty-type backlit keyboard.
Enterprise Improvements
On the phone side of the equation, Sprint's CDMA version of the Treo 650 sports a speakerphone for hands-free operation as well as support for speed dialing and three-way conference calling. The end user can assign an individual button on the handset to a particular phone number or dial phone numbers directly from inside an e-mail message, where they are displayed as clickable hot links.
