The Dell Axim family of personal digital assistants was Dell's line of Windows Mobile-powered Pocket PC Devices. The first model, the Axim X5, was introduced in 2002, while the final model, the Axim X51, was discontinued on April 9, 2007.
Dell entered the personal digital assistant (PDA) market in 2002 with the debut of the Axim X5. The base-level Axim X5 had a 300 MHz Intel XScale PXA250 processor, 32 MB RAM, 32 MB flash ROM, a Type II CompactFlash slot, an SD/MMC slot, a 16-bit QVGA (240 × 320 dots) TFT display, a speaker, a microphone, and a base price of US$279. A high-end Axim X5 came with a 400 MHz Intel XScale processor, 64 MB RAM, and 48 MB flash ROM for US$349. Early models shipped with Pocket PC 2002, but an upgrade to Windows Mobile 2003 was offered and came preinstalled on some refurbished units. Despite rumours and speculations, further versions of Windows Mobile are unsupported. However, efforts have been made to port Linux to the system. Although the Axim X5 was regarded as an affordable Windows Mobile device at the time it was released, affordability came with a size penalty: The weight was 195 g (6.9 ounces) and the size was 127 × 81 × 18 mm (5 × 3.2 × 0.7 inches). The Axim X5 came with a rechargeable battery that would last for about 8 hours.
The Dell Axim X5 was superseded by the Dell Axim X3 and subsequently X30, a follow-up to the Dell Axim X5 boasting a more compact design and with lighter weight.
Many Dell Axim x5 units have issues with the touchscreen failing and a realignment failing as well, even after a hard reset. There is a design flaw inside the unit that causes this. The inside portion of the home button will rub against the touchscreen ribbon cable and eventually wear through the protective coating and ground out the touchscreen. The fix is to take the unit apart and put a very small piece of electrical tape over that portion of the ribbon cable. This requires removing both batteries, clearing all data from the device(similar to a hard reset) and delicate work in taking the unit completely apart.
