Zboards are old now. =P
One of my friends has one, and omg, it's so hard to type on. He also has problems w/ getting it put in just right, otherwise the keys won't work. Too much for sth that's not going to be completely reliable. But, it is neat, especially when they have different inserts for different games.
I'm holding out for a much neater keyboard that's supposed to be coming out w/in the next year. I can't for the life of me remember the name of it. Gurr. It'll come to me. But anyways, you can program keys. Different languages, games, even photoshop. And the keys are colored pictures. How cool is this ? VERY !
