Hi,
it's not just attached at the hinge, it also has poppers to keep it attached to the back of the case and a ribbon to stop it opening too far. I suspect removing it from the case would be possible but a bit messy, but you'd still have the popper attachments on the back which would be even messier to remove.
As the stand fastens down at the back, and when you open the case the front cover flips over, the stand isn't obtrusive and I don't think you'd notice it much. There are photos in this thread
