SD Card Functionality on Motorola US XOOMs
The Google Experience Devices like the Motorola XOOM and Motorola XOOM WIFI allow you to write to the SD card from your PC and use the Android File Transfer on Mac or a cable transfer on Windows to transfer files from the Motorola Xoom to the SD Card.
While a user cannot move apps to the SD card, the device comes equipped with 32 GB of on-board memory that provides plenty of storage. Users can also store and play videos or music from the SD card if the content was copied to the SD card via the aforementioned file transfer processes. However, videos or pictures taken from the device itself can only be saved to the internal memory and not to the SD card.
