It's been nearly three years since we reviewed the Dell Axim X51v, the now-discontinued high-end PDA. HP's latest handheld, the iPAQ 210, has a spec sheet that's remarkably similar: a Marvell 624-MHz processor, a 640-by-480-pixel VGA screen, built-in Wi-Fi and Bluetooth, and an SD card slot are among its features. Look more closely, however, and you'll see some real improvements: The CPU is a next-generation PXA310 instead of the more common PXA270, the iPAQ's Bluetooth spec is now 2.0, and the SD slot is SDIO-compatible. In fact, as it turns out, the iPAQ 210 is a significant leap from both the Axim X51v and HP's own three-year-old iPAQ hx2795 (even more so with the latter, since the hx2795 had only a 320-by-240-pixel screen and 64MB of RAM). Despite some mixed performance results, for those who still need a standalone PDA—particularly in the enterprise market—the iPAQ 210 is tough to beat.
