The announcement will be made at the Comdex tradeshow in Las Vegas on 18 November.
Whether or not Dell can duplicate its desktop success remains to be seen, but its sights are clearly set on knocking out market leader Hewlett Packard's iPaq, which runs Microsoft's Pocket PC 2002 operating system.
Two versions of Dell's Axim X5, priced at $299 (£191) and $199 (£127), are also based on Pocket PC 2002 Professional operating system. The price points undercut the least expensive iPaq 3830 model which sells for $359 (£299).
Eager to point out the differences, Dell executives are encouraging a comparison between the two devices.
The $299 Axim X5 will include a 400MHz Intel StrongArm processor, 64MB of SDRAM, and both a CF2 (CompactFlash) and SD (secure digital) expansion slots. The $199 Axim X5 uses the 300MHz StrongArm processor and 32MB of RAM.
Meanwhile, the $359 iPaq includes a 206MHz StrongArm processor and 32MB of SDRAM and only an integrated SD slot. The iPaq 3870 sells for $650 (£415) and includes 64MB of RAM and integrated Bluetooth.
The Axim X5 does not include any built-in wireless capability.
HP can be expected to introduce lower-priced models, according to Jack Gold, vice president at Meta Group in Boston.
While Gold said HP "will not sit still" on pricing, he also believes that a future enterprise scenario will likely see purchasing agents getting the hardware from Dell and the services from HP. "That's how they do it today," said Gold.
After price, the single most significant difference between the 6.9 ounce Axim X5 and the iPaq which is about 10 grams lighter, is probably the ability of the Axim X5 to recharge the battery without the need to dock or cradle the entire handheld device.
The removable battery has its own slot in the cradle which gives a mobile worker the ability to use a second battery while the first recharges. The lower-cost Axim X5 does not include a cradle, only a rechargeable AC adapter.
Both Axim units measures 5x3.2x0.7in thick and have a 3.5in TFT display, as opposed to the iPaq's 3.8in display
Reflecting on the recent slowdown in handheld sales, Dell's Macon said that Microsoft has not done a good job in marketing its Pocket PC to consumers. Dell believes it will sell as many as 140,000 units from an initial ship date of 25 November to 1 January.
Macon also admitted that from a "one stop shop" perspective it was time that Dell offered a handheld device.
Dell is also offering two batteries — a 3,400 milliamps battery lasting 25-26 hours and a 1,440 milliamps lasting eight to 10 hours.
In autumn 2003, Dell will offer a model with integrated Bluetooth and Wi-Fi with a hardware-software switch between the two, said Macon.
