One of the cool things about the iPad Smart Cover is that it's minimalist. It's not bulky and does a perfectly fine job protecting your screen, not to mention it is good enough to prop your iPad up for web surfing or for watching movies. The downside to the original Smart Cover is that it left the back of the iPad exposed and open to scratches, but the good news is that Apple has since introduced a new iPad casing that not only will protect the front, but the back of the iPad as well.
