Summary: I have used a zboard for years. I upgraded it with each WoW expansion. With cataclysm I bought the new keyset, and put it on my zboard. I had to uninstall the zboard software and install the steelseries engine. This took several tries before it took. I felt I was missing some of the functionality because the cataclysm board was actually made to be compatible with the shift keybase. I bought a Shift, and the problems just keep mounting.
