A workaround to allow the SD card to integrate properly with the OS? That's absolutely unacceptable, and I'm starting to have my doubts about Windows tablets as a whole at this point.
What's the average consumer going to do when they can't download any more music and videos from the Xbox apps because the OS doesn't allow the card to be used as actual expandable storage?
It works the same as if you put a SD card or a USB stick in your PC or MAC, I think people know how to use those
