Is it a PDA or a PMP? It’s very hard to tell with the new iPAQ rx4000 from HP. The Mobile Media Companion is clearly positioned to compete with the Sony Mylo. The device has a 1.8 inch anti-glare touch screen which can be viewed in both portrait and landscape. It runs on Windows Mobile 5.0 and is able to play pretty much any video or audio format that you could want to watch or hear (with one obvious exception).

This isn’t just a PMP, though. It can support Office Suite programs for all your mobile productivity needs. It also makes it very easy to stay connected, offering WiFi and Bluetooth. That means that you can surf to your heart’s content, check your e-mail and download all those things that you wouldn’t tell your mother (or boss) about. The rx4000 isn’t a smartphone, but the WiFi means that you can make and receive VoIP calls as well.

Update: According to Brighthand, the rx4000 is a regional product available in the APJ [Asia Pacific Japan] market. It is not available outside of select countries in APJ.

A version similar to this device, let us call it the
rx5915, could be released to additional countries. However, HP is unwilling to discuss anything further at this time.
