Details on the iPAQ rx4000 model families?

HP rx4000

A tipster I will call OG has let me know that the new HP iPAQ rx4000 Mobile Media Companion series will consist of two lines: The rx4200 and the rx4500. Unfortunately, OG did not have any details about what the differences could be. I wonder if the difference could be tied back to the amount of Flash ROM given that we have seen it range from 128MB to 1GB?

Stay tuned! I’m sure we’ll hear more about this rx4000 and its bigger cousin, the iPAQ rx5000 Travel Companion.
