This new line of consumer-oriented HP iPAQ devices is growing into a family right quick. We just saw the rx4000 a couple of days ago, and now we're catching wind of at least a couple rx5000 devices. The rx5000 types go with the "Travel Companion" moniker, since they include a SiRF Star III GPS receiver for a bit of navigation action. WiFi seems to be optional for the rx5000 units, but the rx5915 has it, along with a 3.5-inch QVGA touchscreen, 2GB of flash memory, 64MB RAM, Bluetooth 2.0, SDIO slot, standard 3.5mm headphone jack and a 400MHz Samsung processor. Hopefully these specs give us a better indication of what HP is packing in the rx4000 units, and the flash memory size does appear to be a variable, so we're guessing we'll at least get a 2GB option in rx4000 land. The Travel Companion iPAQs feature a traditional 9-way direction pad, along with 2 Windows Mobile buttons, but none of the rx4000's jog dial action. As for price, the rx5915 weighs in at a hefty, if almost reasonable, $600. We've been hearing some rumblings about whether or not these new iPAQs were going to make it to the States, but we can at least say that the documentation we've seen shows off the rx5000 nav features gallivanting around North America, so we've got that going for us.
