I understand that in the UK, this will be announced and ship in May, I'd assume similiar dates for the US. This is the second in the long delayed new iPAQs that were origionally meant to ship last year!

Unlike the 614c the 900 will be available in the US, and the
documents/pictures filed with the FCC, show a few minor tweaks to it's shape. It will also run Windows Mobile 6.1. The full HP Quickspecs show:
