Dell's OEM version of the TO BT keyboard is black. Same unit, different colour. Possibly a different version of firmware on board, to accomodate Axim-specific quirks. Can be re-flashed with the TO version of the firmware if you so desire. (I stuck with the Dell firmware

)
BTW: The stand that comes with these keyboard has a nasty design flaws that result in cracks. ThinkOutside is supposedly reworking the design. In the meanwhile if you e-mail them they will send you a couple of replacement ones in the mail. Other than the cracking stand issue, they are excellent keyboards.
