We were introduced to the new HP iPAQ rx4000 earlier this week, we just came to learn that the 
model will be a regional product available in the APJ [Asia Pacific Japan] market. It is not available outside of select countries in APJ.
However, HP has already released a newer and bigger member of the product line. The rx5915 is known as a ‘Travel Companion’ because it adds a SiRF Star III GPS Receiver to the range of entertainment options available in the rx4000. [tag]HP iPAQ rx5915[/tag]HP iPAQ rx5915 - the rx4000 on steroids
