The Pandora, which has the same processor and the same principal designer (i.e. Nikolaus) as the Neo900, has the sys_boot5 pin linked to the START button. This means that if one holds down that button while powering on, the system boots from the SD card rather than the internal Flash. I, for one, find this very useful. If it is not already happening on the Neo900, I would like Nikolaus to please consider it.
