I have been very happy with the Acase Leather Flip Book Jacket. It is a no-frills cover that flips up to hold the device in various positions. As a nurse who is aware of and complies to good ergonomic practices, the flat position is my favorite for typing. I can easily access the on-off button and plug the cord in without any issues.
