Hey I have an iPad with a Smart Cover and preferably need something to protect the back. If you could point me to some good sleeves, bags and just any case which will cover the back and let me keep my smart cover in use I would appreciate it, thanks. I don't need the back covered at all times, just at least while its being transported about in my bag for example which is why Im ok with sleeves. Price isn't an issue either so more premium options are cool. Thanks.
