During the iPad 2 announcement Apple introduced "Smart covers" almost as a standalone product; and I have to admit, they kind-of stole the show... that is until they mentioned... the prices. So, I have been thinking, are Apple's "Smart Covers" worth it? Especially at that price?? Also, what do you guys think of their design (quality of materials, color choices, etc..) and utility (effectively being able to protect the device, magnetic alignment, etc..) and how Apple can possibly improve them. I, personally, wouldn't get one for more than $20 ($30 for leather.) Otherwise I like the design and general functionality of it.
