A few more details about the upcoming HP iPAQ rx4000 Mobile Media Companion have surfaced. A Chinese site based in Hong Kong is indicating that the rx4000 will use a 400MHz Samsung processor. More interestingly, it appears that at least one model will come with 1GB of ROM (in addition to the 128MB ROM mentioned earlier).
I’m hoping that the rx4000 will support SDHC as this would provide up to an additional 32GB of memory (when the cards come out). If not, the limits of SD will limit storage to an additional 2GB.
