Palm’s Best
The Palm Z22 & Palm TX Compared
Jump to first occurrence of: [PALM] [Z22]


When Palm’s Pilot came out in 1996, it became an instant status symbol. Today, you don’t need to be a professional to justify owning a PDA. Palm offers a range of models for users with different budgets. We’ll look at Palm’s entry-level unit and one of its high-end models to show you what each has to offer.

Palm Z22

Palm’s Z22 focuses on personal organization. It doesn’t play music or video clips, but it can display digital images and organize your personal information and costs less than $100.



Not many extras at all. The top of the Z22 features a mini-USB connector and a slot for stylus.

Specifications

OS: Palm OS 5.4.

Memory: 32MB of nonvolatile memory with 20MB free for applications and data.

Processor: 200MHz ARM (Advanced RISC [reduced instruction set computing] Machine)-based.

Display: 2.5-inch CSTN (color supertwist nematic) display (160 x 160 resolution; 4,096 colors).

Battery Life: One week on a single charge.

Communications: USB.

Multimedia: Digital images.

Software: Palm Addit, Astraware Crazy Daisy, Power By Hand eReader, Handmark Mobile DB, Palm Photos, PowerOne Calculator, SplashData SplashShopper.

Size: 4.06 x 2.7 x 0.6 inches (HxWxD).

Weight: 3.4 ounces.

Hardware

The Z22 lacks the multimedia and networking capabilities found in high-end models such as the Palm TX. Compared to the TX, the low-resolution display makes images, icons, and text look jagged and pixilated. The backlit display disappears entirely in bright sunlight.



The Z22 features a very clean, almost iPod-like design.
The Z22 has 32MB of memory, but it uses 12MB for the OS and core applications. We did appreciate the fact that Palm used nonvolatile memory for the Z22. That means you won’t lose any data if your battery dies while you are using the device.

Battery Life

As much as we disliked the display, we loved the Z22’s battery. You can easily go a week without recharging it, and maybe more. The smaller display and nonvolatile memory almost certainly improve the battery life. The Z22 includes a single mini USB connector that accommodates a USB cable or an AC adapter.

Software

The Z22 comes with the basic Palm apps including Calendar, Contacts, Memos, and Tasks. The Z22 also includes Addit, which lets you select applications you want to try or buy. Addit downloads selected applications during HotSync.

The Z22 includes a Palm-branded version of Photos for organizing and displaying digital images on the Z22. Images, however, look washed out and jagged on the low-grade display.

Overall

Although we didn’t care much for the display, we loved the battery life, the nonvolatile memory, and most of all the price. At $99 the Z22 is a perfect entry-level PDA for someone who’s looking to dump his bulky paper organizer.


Palm TX

The only difference between the Palm TX and Palm’s high-end LifeDrive is that the TX doesn’t include 4GB of storage. The TX, however, has many of the same multimedia and networking features included with the LifeDrive.

Specifications

OS: Palm OS 5.4.

Memory: 128MB of nonvolatile memory with 100MB free for applications and data.

Processor: 312MHz ARM-based

Display: 3.8-inch transflective TFT (thin film transistor) display (320 x 480 resolution; 65,536 colors).

Battery Life: About 5 days of moderate use.

Communications: USB, Wi-Fi, and Bluetooth.

Multimedia: Digital images, audio, and video.

Expansion: SD card.

Software: Palm Addit, Palm Blazer Web browser, Palm Bluetooth Manager, DataViz Documents To Go Professional Edition, Palm Media, Power By Hand eReader, NormSoft Pocket Tunes MP3 Player, Palm SMS (Short Message Service) messaging, Palm VersaMail email client, Palm Wi-Fi Manager, Hands High Software WiFile LT.



The Palm TX includes a much larger, better quality display in addition to advanced networking and multimedia capabilities.
Size: 4.76 x 3.08 x 0.61 inches (HxWxD).

Weight: 5.25 ounces.

Hardware

The Palm TX is larger and heaver than the Z22, but it’s worth the extra heft. The TX includes multimedia and networking capabilities as well as a bigger, brighter, high-res display. The transflective TFT display is bright indoors and remains readable in sunlight.



On the top of the Palm TX, you’ll find an SD slot for extended storage and a stereo headphone jack in addition to the recessed power button.
The TX supports Blue-tooth for connecting to other Bluetooth-enabled devices including notebooks and cell phones. Wi-Fi support lets you connect the Palm TX to 802.11b wireless access points. After connecting to to the Internet, you can send and receive email using Versa-Mail or surf the Web using the Blazer Web browser.

The Palm TX uses Palm’s Universal Connection Slot, so the device is compatible with Palm’s optional cradle. nonetheless, we were a little disappointed the TX didn’t come with its own cradle. An extra $49.99 is a bit pricey for a cradle. Then again, the USB cable is much easier to pack.

Battery Life

Battery life is the one area where the Z22 manages to beat the TX. We ran a continuous slideshow on both models and got an extra hour or two from the Z22. According to Palm, you’ll get about five days of battery life from the TX with moderate use, but you should expect to recharge every day or so if you use the TX’s multimedia or networking features.

Software

The TX also comes with a lot more software than the Z22. DataViz’s Documents To Go lets you edit or create Microsoft Office documents (including PowerPoint presentations). Pocket Tunes is a great audio player, and Palm’s Media software lets you view images and watch video clips on your TX.

Overall

The Palm TX is a formidable package, but at $299 it’s also significantly more expensive than the Z22. Nonetheless, if you need networking and multimedia capabilities, as well as a better display, the TX is the way to go.
