Dell Axim x50 and Hewlett-Packard's (HP's) iPaq hx2700 use the new version of Pocket PC and include Wi-Fi Protected Access (WPA) support for the devices 802.11b connections. The WPA support was tested on both devices and worked perfectly. Microsoft has added useful improvements to the Pocket PC platform, but large segments of the platform, including Pocket Word and Excel applications, seem to have remained the same for several years. Microsoft should also change the Pocket PC interface, which is also identical to the original version. Neither the iPaq nor the Axim has an interface as uncluttered and appealing as that of the Tungsten T5. However, with better network connectivity choices, which are available in both devices with Bluetooth and 802.11b radios and Secure Digital and Compact Flash slots for peripheral expansion, iPaq and Axim will work very well for data collection reference and as supplements to the desktop PC. The iPaq has an Intel 624MHz PXA270 processor and 128MB ROM, with 128MB SDRAM. Overall half of the ROM can be used for file storage. Data stored in handheld device ROM, rather than RAM, is retained in the event of a power loss, which occurs frequently with handhelds. Both devices have the standard buttons, and testers could reassign all buttons on each. Both have color, quarter-VGA displays, and, with the installation of Windows MOBILE 2003 SE, these and other Pocket PCs support switching between landscape and portrait modes.
