@bocaJ: Doesn't the N900 have a microSD port in one of the sides? From the specifications it says there are two microSD expansion slots, one internal upto 32Gb and another one external upto 16Gb. From the 3D model in http://maemo.nokia.com/n900/360/ the external slot doesn't seem to have problems for this device to connect.

@Matan: From the producer specifications page it seems 32Gb is the limit, as it is the limit for the SDHC host. Anyway I imagine the N900 external microSD slot would limit this to 16Gb.
