One of the things that made OpenMoko's FreeRunner interesting was that it was also an open hardware platform - all parts used had publicly available documentation, there was a debug port with direct access to all low-level hardware, and effort was made to make it hardware-hacker friendly. The N900 looks nice, but it's not near as open as the FreeRunner.
