<<<...The iPAQ rx4000 Mobile Media Companion, a PDA/media tool, and rx5000 Travel Companion intended to function as PDA/GPS units came out in February of 2007, both working on Windows Mobile 5 OS. A month later, HP came out with their first Windows Mobile 6 device, the iPAQ 500 Series Voice Messenger (Windows Mobile 6 Standard OS). It also had a numeric pad. The only iPAQs being sold today that run the Windows Mobile 5 OS are the hx2000 series, the rx5900 series and the hw6900 series. Since the introduction of the new devices in February of 2007, the entire iPAQ line has been revamped. A dizzying five new series have emerged to go with the iPAQ 500 Series Voice Messenger.
New models:
* 100 Series Classic Handheld
* 200 Series Enterprise Handheld
* 300 Series Travel Companion
* 600 Series Business Navigator
* 900 Series Business Messenger
The 100 and 200 Series are touchscreen PDAs and do not have phone capability. They run on the Windows Mobile 6 Classic OS. The 300 Series Travel Companion is not a PDA. Called a Personal Navigation Device, it is a GPS unit and operates on the Windows CE 5.0 core OS and has an HP custom user-interface. The 600 and 900 are phones with GPS and 3G capabilities. They run the Windows Mobile 6 Professional OS. The 600 series has a numeric pad; the 900 has a QWERTY keyboard.
