Editors' note: This review is based on the US GSM version of the PalmOne Treo 650. Unlike the US version, the Asian model allows for dial-up networking over Bluetooth. In addition, local sets will not come with a free 128MB SD card from PalmOne.

When we made our wish list for the successor to the well-received Treo 600, it was to keep the great design but add several missing features. Fortunately, that's precisely what PalmOne did with its new Treo 650. This model offers a high-resolution display, a faster processor, Bluetooth wireless, Palm OS 5.4, and a removable battery--all notable additions. But the honeymoon ends with some shortcomings, specifically the stingy memory, the limited Bluetooth implementation, and the lack of Wi-Fi. How you feel about these issues depends on your needs, but for our money, the Treo remains the best all-in-one communicator available.

Design
The PalmOne Treo 650 looks virtually identical to its predecessor. It is the same shape and size (113 x 59 x 23mm, not including the stubby antenna) and only a hair heavier at 178g. In fact, it looks so similar (except for a slight color change) that during testing, bystanders often did a double take and even then had to ask, "Is that the Treo 650?" No wonder--why tinker with a design that has stood the test of time? Of course, the Treo 650 is not the most compact smart phone on the market; Windows Mobile 2003 smart phones such as the O2 Xphone II are significantly smaller, though they don't have a full QWERTY keyboard.

Still, there are some notable changes to the design. The most impressive new feature of the Treo 650 is its improved display. It is the same size (2.5 inches diagonal; 320 x 320 pixels) but now shows off 65,000 shades, compared to 3,375 hues on the Treo 600. The result: smooth, bright, and colorful images with no trace of the "screen door" effect on the Treo 600's display. Overall, the new display is on a par with that of the latest high-end handhelds--something that couldn't be said of the previous version at the time of its release. Another obvious change is the keyboard. The keys have been squished so that they are larger, flatter, and closer to one another. The keyboard still feels cramped, but generally, these enhancements make thumb-typing a little easier than with the Treo 600. The new white keys are also semitranslucent with bright backlighting.


The Treo 650 retains the signature five-way navigational button, which is critical for easy one-handed operation. But there are several new buttons as well. The most prominent are the dedicated Talk and Power/End buttons, which operate much like those on most cell phones. Four buttons directly below the display provide quick access to the calendar, messaging, applications, and menus. And the volume buttons on the side have been replaced by a single rocker switch, which is easier to use, as well as one customizable quick-launch button (by default, it opens the Web browser).

We were pleased to see that PalmOne kept the hardware switch on top that toggles between ringer and silent modes--a handy feature--along with the MMC/SDIO expansion slot and the infrared port. The camera is located in the same spot on the back panel but now has a tiny mirror for self-portraits; PalmOne will also offer a camera-less version for execs worried about security risks. The speaker and the panel for accessing the user-removable battery are immediately below the camera. Farther down on the bottom are the new Multi-Connector, for synchronizing and charging the Treo and connecting accessories, and a headphone jack. The Multi-Connector, first introduced on the Tungsten T5, replaces the unfortunately named Universal Connector of previous PalmOne devices, and it is not backward compatible. A minor inconvenience, the 2.5mm jack requires an adapter (not included) for use with standard headphones.


There's still no included cradle for charging or syncing. Instead, PalmOne includes USB and power cables that can be connected to each other or used separately. As with the previous version, the touch screen is unprotected and tends to get covered with dust and fingerprints quickly. You'll want to purchase a slipcase for it immediately since one isn't included.

Features
The PalmOne Treo 650 has a generous feature set, but we weren't completely in awe. We like the new 312MHz Intel PXA270 chip processor that provides the muscle for multitasking and digital audio and video applications. The memory, however, is another story. First, PalmOne did not increase the amount of memory in this version. In fact, the Treo 650's 22MB of usable memory is slightly less than the Treo 600's total after you take away what the OS and core applications require. Second, the company switched to a new file system that effectively reduces available memory by increasing file sizes. (There is a detailed explanation here.)

There is a good reason for this: the new nonvolatile file system (NVFS), paired with the 22MB of nonvolatile memory, means you no longer lose all your data if the battery dies or if you want to swap in a fresh battery, which wasn't possible with the Treo 600. In other words, the Treo 650 acts more like a cell phone and less like a handheld that needs to be tethered to a PC at regular intervals to recharge and to back up data. This is especially good news if you use client-server software that syncs directly with Microsoft Exchange Server wirelessly, such as ActiveSync for Exchange Server 2003 (now included) or GoodLink. In that case, you will need to HotSync with your desktop only to install new applications or to transfer large files.

Nevertheless, the memory has caused a lot of hubbub, especially among Treo 600 users who upgraded, then discovered that their files suddenly gobbled up more memory. PalmOne is promising a ROM software update to alleviate the problem. Whether you get it from PalmOne or buy it yourself, the bottom line is that a nice, big SD card is a must-have accessory for the Treo 650.

In addition to wireless WAN voice and data, the Treo 650 includes both infrared and the much-needed Bluetooth. Theoretically, Bluetooth lets you do several things wirelessly: perform HotSyncs, connect to other Bluetooth devices, hook up headsets, and use the Treo as a modem with a Bluetooth-enabled laptop. But that's just the theory, as the implementation is not ideal. We tried using the Jabra BT250, the Logitech Mobile Bluetooth headset, and the Jabra BT800. Pairing with each device was problem-free, and calls came through loud and clear. Additionally, on the BT800, we were able to place calls directly from the headset.

Using a headset wasn't perfect, though. Even though the documentation states that calls can be automatically routed to a connected headset, not all headsets support this hands-free operation; instead, you must press a button on the headset to make or receive calls. (PalmOne maintains a compatibility list in the support section of its site; the ones labeled "Handsfree supported" offer the most features.)

The bigger issue is that you can't use the Treo 650 as a wireless modem for your laptop when you are on the road and there are no Wi-Fi hot spots within range. Also, you can't use Bluetooth to connect to stereo headphones or a keyboard.

Much to our disappointment, there's still no integrated Wi-Fi, a feature that has become a common in midrange and high-end PDAs. At some point, the PalmOne SDIO Wi-Fi card will work with Treos, but the company has been slow to release the drivers, and you'll still have to pay for something that arguably should be built in. That said, improvements to the WAN data networks along with the addition of Bluetooth lessen the need for Wi-Fi.

More Features
The basic phone and handheld functions of the Treo remain the same. You get many of the features of an advanced mobile, including a phone book (size is subject to available memory), 28 polyphonic ring tones, a speakerphone, vibrate mode, three-way calling, speed dial, and picture caller ID (where available). And you get the features of a handheld running Palm OS 5.4. Aside from basic organizer applications such as a task list, memos, a calculator, an alarm clock, a calendar, and a world clock, the Treo 650 includes the excellent Dataviz Documents To Go 7.0 for viewing Microsoft Office documents, VersaMail 3.0, AudiblePlayer, and support for Java (J2ME)-enabled games. Multimedia capabilities also got a boost. Previously on the Treo 600, you had to download a third-party application to listen to MP3s; now, the Treo 650 includes RealPlayer in ROM for playing MP3s or Real files. Audio automatically stops when a call comes in.

The Treo has always been an e-mail machine, but VersaMail 3.0 ups the ante. In addition to its support for up to eight POP and IMAP accounts, it now works with ActiveSync for Exchange, which means that with a little help from IT, you can connect directly to your company's Exchange Server 2003. PalmOne also includes a convenient single in-box for text and multimedia messages. The WAP 2.0 wireless Web browser is largely unchanged in appearance, though the device supports both GPRS and EDGE networks.

Though many cell phones now come with 1.3-megapixel cameras, PalmOne stuck with a VGA camera, which disappointed us somewhat. The company made some notable improvements, though. The camera performs better in low light, can shoot video (in MPEG-4 format) as well as stills, and includes a tiny mirror for self-portraits. We especially liked the included picture and video-viewer application, which can play slide shows and even set them to music.

Performance
The PalmOne Treo 650 is available as a quad-band (GSM 850/900/1800/1900; GPRS/EDGE) world phone. We tested the GSM model for Cingular Wireless--it's the second version available--in San Francisco.The overall call quality was admirable, whether we were holding the unit to our ear or using the speakerphone, the included wired earbuds, or the optional Bluetooth headsets.

The Treo 650 is rated for 6 hours of talk time and 12.5 days of standby. The talk time was 4.25 hours in our tests, though the standby time seems a little optimistic. The Treo 650's battery is now removable, so you can swap in a spare on long trips. It has a SAR rating of 1.51W/kg.

The Treo 650 is available at a recommended retail price of S$1,188 without contract.
