Anyone have any experience using KB Covers? I've been looking into possibly getting one of their covers for my computers. I searched the forum but really only found one person who uses one. My main concern would be issues regarding marring the screen and the feel when typing. I'm actually looking at the Hiragana one they have so I won't be typing blind when I'm typing in Japanese. I also thought about swapping the keyboards with a Japanese version, but this keyboard cover would be quite a bit cheaper. Any help would be greatly appreciated.
