Dell Axim X51 series
Over the past year, Dell has earned a reputation for producing some of the best PDAs on the market--first with the high-performance and the recently discontinued Dell Axim X30 series, then with the versatile Dell Axim X50 series. Now, the company is out with the new Dell Axim X51 series. Although these Pocket PCs keep the same design as the X50 series, they have plenty of new features. They come with a more robust software bundle and are the first stand-alone PDAs to run the Windows Mobile 5 operating system. Unfortunately, the X51v suffered from subpar battery life and sluggish performance in our tests. That said, with everyday, casual use, the Axim X51 series--the high-end Dell Axim X51v ($499), the middle-of-the-road Dell Axim X51 ($399), and the entry-level Dell Axim X51 ($299)--includes very capable PDAs that should fit the needs of consumers and business users alike. When it came to the Dell Axim X51v's design, Dell decided to go with the philosophy of "If it ain't broke, don't fix it." The Axim X51v's styling is nearly identical to the X50's, keeping the sexy black and silver color scheme and aesthetically pleasing rounded edges. The X51v is just a hair thicker than its predecessor (4.7 by 2.9 by 0.7 inches and 6.2 ounces), but it won't weigh you down. It's also a solidly built device that's comfortable to hold, and we like the rubberized backside cover for better gripping.
The star attraction on the Dell Axim X51 is undoubtedly its 3.7-inch VGA screen. Thanks to a 640x480-pixel resolution and a 16-bit-color output, you'll enjoy sharp text and images, and there's continued support for landscape and portrait modes. Below the display are your standard shortcut keys to Calendar, Contacts, Inbox, and Home, plus a four-way navigation toggle with a center Select button. Although we criticized the Axim X50 for its diminutive toggle, by now we're used to it, yet we still caution users with bigger fingers. A speaker, a power button, and a status LED line the top edge of the PDA's face.
It's easy to access many of the Dell X51v's features with a click of a button. Aside from the aforementioned shortcut keys on the front, there are two buttons on the left spine that activate the voice recorder and wireless connection. There's also a hold button, which is always appreciated, since it prevents any unnecessary battery drain if the device is accidentally turned on. On the top of the Axim X51v, you'll find a 3.5mm jack that accepts Walkman-style headphones, dual CompactFlash and SD expansion slots, and the stylus. The handheld's battery is user-replaceable, and you can swap out cells by unlocking the sliding battery-release lever on the back.
Dell provides all the basics to get you started. Accessories in the box include a soft protective case, a desktop-synchronization cradle, a power adapter, and a companion CD. The cradle has an extra slot for charging a second battery, which is nice. A high-capacity cell is available for $99 and promises to double battery life. Other optional accessories are available, such as a GPS navigation system (Bluetooth or wired), a Bluetooth keyboard ($99.95), and a presentation bundle ($49).The Dell Axim X51v's biggest makeover is in the features department. Some elements remain the same, though, such as the 624MHz Intel XScale PXA270 processor and the Intel 2700G graphics engine. Also, there's still 16MB of dedicated video memory and 64MB of SDRAM, but the really good news is that Dell bumped up the flash ROM from 128MB to 256MB, 192MB of which is user-accessible. This, coupled with the dual expansion slots, amount to ample storage space. Another thing that helps is the addition of the Windows Mobile 5 operating system. The new OS has built-in support for persistent storage, so when the battery drains completely, your data remains intact.
With Windows Mobile 5, Microsoft also swapped out Pocket Word and Pocket Excel in favor of a new Office Mobile Suite that includes Word Mobile, Excel Mobile, and PowerPoint Mobile. Yes--PowerPoint. Although you can't edit slides, you now can view presentations right on your PDA. We gave it a whirl, and we were impressed not only with the ability to watch slide shows but also with the various options. You can skip directly to specific slides, change the orientation, and choose playback options, such as loop, turn off/on animation, and zoom in/out. The last option is particularly handy, since a thumbnail of the slide is presented in the lower-right corner of your screen. What's more, you can choose particular spots on the page to zoom or automatically go back to the full slide. Unfortunately, these tasks seemed to take a lot out of the Axim X51v, as there was a noticeable delay in response time (see Performance). As for the other applications, Word Mobile now supports documents with embedded images and tables, plus Excel Mobile handles charts. We put these applications to test, and while the experience was not ideal, given the size of a PDA's screen, we were able to open and view tables and charts in all our documents.
