Material difference btw Black & Color Touch Covers

In one of the reviews, it was mentioned that the black touch cover is a felt material and the color touch covers are basically a rubber/plastic material.

Maybe I missed it, but that wasn't mentioned in the pre-order. I picked Cyan, but i really wanted the soft felt feel.

I would have been nice if we knew this before the pre-order. I guess i could have waited, but it's a small gripe.
