Retractable buttons on a flatscreen ?

I just got done checking out the video below and I am very impressed. If this works well it will be a game changer. I remember living off of my Blackberry Curve and typing faster on that mini keyboard than I could on my laptop, and then purchasing an iPhone 3G. I had the hardest time adapting to that new keyboard that had no feeling to it. Now I am seeing an amazing combination of both worlds ! I will be one of the first to try this out. Very Cool !
