HP unveiled its updated hx2000 lineup in late September. Mobile Tech Review got their hands on the new middle-of-the-range hx2490 and put it through its paces. They have benchmark results, take a look at expansion and WiFi and Bluetooth (HP kept the Broadcom user friendly Bluetooth Wizard) capabilities and look at how some software fares under Windows Mobile 5.0.
I think that they like the iPAQ hx2490: The only con they list is that there is not much of a software bundle by HP standards.
