If you are looking for protection for your new iPad 2 that can be used with Apple Smart Case, Fabrix may have a solution for you with their sleeves.
Cindy Downes reviewed their sleeve last year which can be found in the below link.
These sleeves are compatible with both iPad versions.
You can also check out my past Fabrix Booklet review below here for the iPad 1. I use this case often with the most recent time being on my vacation to Florida two weeks ago. I do not see any of these by Fabrix for the iPad 2 yet on their site.
