I will be receiving a C3000 from Conics.net in a few days, and would like to dump the Sharp ROM ASAP. I know that most of these issues will require research and testing on an actual unit, but I want to get an idea now of how difficult the porting process will be. I will, of course, help out in any way I can (non-technical user).
-C3000 has 16MB Flash ROM, versus the 64 or 128MB in previous C-series Zauri. The 4GB Microdrive is designed to take the place of the user memory (storage), but it is not yet known if any of the OS files reside on the HDD.
-C3000 uses the new Intel PXA270
**EDIT: C3000 uses the built-in graphics of the PXA270; previous C-series Zauri used the ATi Imageon 100
-C3000 has USB Host capability - not present on previous C-series Zauri.
