CNET Editors' Review

The good: Built-in keyboard; 96MB of combined memory; CompactFlash and Secure Digital slots; compatible with Microsoft Outlook and Palm Desktop; excellent audio.

The bad: Big and heavy; dull screen; limited third-party software; lacks jog dial.

The bottom line: By boosting its speed, adding memory, and smoothing out software kinks, the Zaurus SL-5600 Linux handheld offers a challenge to Pocket PCs and Palms.

Review: A year and a half ago, Sharp introduced its Linux-based Zaurus SL-5500, which boasted a 206MHz StrongARM processor, 64MB of memory, and a unique minikeyboard. But lacking the speed, the polished interface, and the software of a Pocket PC or Palm handheld, it merely registered a loud yawn. Enter the SL-5600: an evolutionary development with a 400MHz processor, 96MB of storage, and a slew of software. It is now one of the fastest and best-equipped handhelds available, though it's a bit big, needs a brighter screen, and can't touch the established order's third-party software.

A year and a half ago, Sharp introduced its Linux-based Zaurus SL-5500, which boasted a 206MHz StrongARM processor, 64MB of memory, and a unique minikeyboard. But lacking the speed, the polished interface, and the software of a Pocket PC or Palm handheld, it merely registered a loud yawn. Enter the SL-5600: an evolutionary development with a 400MHz processor, 96MB of storage, and a slew of software. It is now one of the fastest and best-equipped handhelds available, though it's a bit big, needs a brighter screen, and can't touch the established order's third-party software.

Big and bulky: The Zaurus is not quite as big as a breadbox.

Slumbering giant: However, it is large, heavy, and thick.

At 5.4 by 2.9 by 0.9 inches and 7.8 ounces, the sleek, silver Zaurus SL-5600 is not only thicker and heavier than its predecessor, it makes handhelds such as Toshiba's e750 and Palm's Tungsten C look compact. It's also nearly twice the weight of Handspring's Treo 90. Add in the 7-ounce AC adapter and cord, and the SL-5600 hits the ground stumbling at close to a pound.


The SL-5600's accurate 3.5-inch touch screen is the center of attention, though it's an older, reflective TFT rather than a new, transflective display. While we liked the clear-plastic screen cover, it comes off all too easily and doesn't form a stand when you flip it over. Pull down the bottom of the unit, and you'll find a minimalist, 37-key QWERTY keyboard. At 4.7mm across and spaced 2.4mm apart, the oval, Chiclet-style keys are sufficient for tapping out one-line e-mails and short lists but too cramped for marathon typing. The SL-5600 has reasonably accurate handwriting recognition, and there's a handy place to stash the stubby plastic stylus. While the onscreen keyboard is not much help, the PickBoard predictive spelling application helps find common words.

The clear-plastic cover protects the screen, but it comes off too easily.

A cradle and cables accompany the Zaurus, but you may recharge it via the AC adapter.

In addition to dedicated Calendar, Contacts, Home Screen, and Email keys, as well as a program launcher, the SL-5600 has a five-way navigation button. But its most notable absence is a side jog dial for quickly running through lists or Web pages. A standard headphone jack is conveniently placed at the top of the unit, and the rear speaker is surprisingly loud. On the other hand, the SL-5600's microphone is pointed to the side and back, so it's likely to pick up stray noise.

The SL-5600 comes with a USB 1.1 synchronization cradle to connect to a host PC. For older computers, Sharp sells a $40 serial port adapter. The good news is that you can plug the AC adapter directly into the SL-5600 when you want to leave the cradle behind. Sharp says the 1,700mAh lithium-ion battery takes up to four hours to charge, but it can rejuice in as little as an hour and can be changed in a few seconds.

Double barrel: The SL-5600 has both CompactFlash and Secure Digital slots.

Lots to do: Here's a view of the device's well-stocked Applications screen.

With a 400MHz Intel XScale processor and 96MB of combined memory (32MB of active SDRAM and 64MB of flash memory), the SL-5600 is one of the best-equipped handhelds around. With the Linux OS and the included applications taking up 34MB, there's still room for additional programs, addresses, appointments, and a backup. If that proves constricting, you can augment your storage with Secure Digital and CompactFlash cards, including IBM's 1GB Microdrive hard disk.

This mighty mite comes with a generous batch of software, including the Opera Web Browser, an e-mail client, a calendar, an address book, and a to-do list. If time hangs heavy, there's a clock and a world-time map. You also get ImagePad, which displays and edits pictures, as well as runs slide shows. It's also excellent for doodling with the stylus. Hancom's Mobile Word, Sheet, and Presenter are competent applications and compatible with their Microsoft counterparts (Word, Excel, and PowerPoint, respectively), but none have spelling checkers.

"It would be better with PocketPC OS" By

Pros: 1) Da keyboard! have you ever tried to update an excell file with the stilus pen? how about configure a router for us geeks, the keyboard is a must. 2) CompactFlash slot, if you need to use a modem or a 10/100 ethernet NIC you need it. (Not all sites are

Cons: Linux-Java OS??? What the H... Very little support on that OS, every needfull application you want to add cost you $29.95 and up. Drivers for some NICs and other periferrals require 3rd party drivers and/or some modification to the Kernell. I'm a geek but

"Best mobile tool" By

Pros: Opera browser by far the best pda internet experience. Excellent software bundle. Twin card slots. Lots of developer support means huge variety of software. Sharp provides regular ROM updates, unlike Palm, Toshiba or HP

Cons: PIM apps not as good as Palm or Pocket PC. No usable SMS application to link with phone.
