I have a clear Joy cover that works perfectly with a Smart Cover (I also added 4 clear stick-on feet to it)
I also bought a CoverBuddy in gray and I like that a little better (I like the rubbery feel of the CoverBuddy) although both really work very well.
I will send the Joy cover for free to the first person who IM's me an address to send it to. I won't use it again and I have years of computer stuff laying around and don't need to add to the collection.
I would rather see a user here put it to good use.
