Maybe if it had the same rough texture of the original casing, I'd like it better. What I think would be really cool would be an aluminum replacement casing just like the original. Ultimately, I went back to my original casing. Not for any real reason, other than I just like the feel of it better. Doesn't require a hard reset to install it.
Case is a bit more flexible than the original.
Let me know your comments on the Clear Palm III Case.
