Has anyone tried it for WoW? Results? Likes? Dislikes?

I was thinking I need to move away from the standard keyboard but would like to be able to control everything in one spot and not have to use WASD, or at least minimize their use. I thought a joystick type deal in the middle of an X-key would be perfect and what do you know, they have one.

For those of you that use a normal X-keys pro, how do you move/strafe?

Anyone know of similar solutions? I know about the Belkin N52s and similar, I have a TE, but sue to issues with my hands those do not work for me well at all.
Thanks
