My mind is racing with all of the creative and fun software possibilities that this type of hardware can enable. The video showed some great examples. At $70, its within a reasonable price point to take off. The only thing I'd be concerned about is arm strain that results from holding your hands in the air like that. After a few minutes, its probably pretty uncomfortable. Does this work even if you rest your elbows on the desk? I assume it would, but the question of arm strain and comfort is the only thing I wonder about.
