Hi, Thanks for your long report and idea skills... Then, any way to make something in the current P900 and its firmware to overpass the 128Mb DUO limitation? New navigation softares are on the way, and for example, if I look at my TomTom for PocketPC, the whole France MAP is 230+Mb, and the whole main streets Europe Map is 70+Mb... Then, a 512Mb DUO Pro would be very nice... Also, if we could find a tip to move Calendar and Contact data from internal to MS memory (at least Contacts), as I could do with my old Psion Series 5, we'd have a P900 with a better breath... Waiting for your thoughts... Pierre
